Our laboratory has developed catalysts based on earth abundant titanium for asymmetric reactions including intramolecular hydroamination. Previously, we showed that titanium complexes of imine diol ligands showed improved enantioselectivity relative to complexes with bidentate amino alcohol ligands. As the catalyst with the highest selectivity had di-tert-butyl substitution, we sought to increase the steric protection by preparing three new ligands with diaryl substitution. These ligands were readily prepared in two steps: first, synthesis of diaryl substituted salicylaldehydes by a Suzuki coupling and second, a Schiff base condensation with a chiral amino alcohol. After characterizing the ligands, in situ hydroamination/cyclization with 6-methyl-hepta-4,5-dienylamine was carried out at temperatures ranging from 105 degrees C to 135 degrees C to give exclusively 2-(2-methyl-propenyl)-pyrrolidine with enantioselectivity up to 22 %ee. Unexpected dimerization of the catalyst resulted in reduced activity, so the reaction required a catalyst loading of 10-20%. (C) 2021 Elsevier Ltd. All rights reserved.

A general and efficient method for the deconjugative alpha-alkylation of alpha,beta-unsaturated aldehydes promoted by a synergistic effect between (BuOK)-Bu-t and NaH, which considerably increases the reaction rate under mild conditions, is reported. The beta,gamma-unsaturated aldehyde, resulting from the alpha-alkylation, is transformed in high yield into the corresponding allyl acetate via a lead(IV) acetate-mediated oxidative fragmentation. This strategy could be used for the construction of the carbon skeleton of a wide variety of alkyl or arylterpenoids.

Recommanded Product: 105-13-5. I found the field of Chemistry very interesting. Saw the article A green approach for aerobic oxidation of benzylic alcohols catalysed by Cu-I-Y zeolite/TEMPO in ethanol without additional additives published in 2021, Reprint Addresses Zhong, W; Liu, XM (corresponding author), Jiaxing Univ, Coll Biol Chem Sci & Engn, Jiaxing, Zhejiang, Peoples R China.. The CAS is 105-13-5. Through research, I have a further understanding and discovery of (4-Methoxyphenyl)methanol.

An efficient and green protocol for aerobic oxidation of benzylic alcohols in ethanol using Cu-I-Y zeolite catalysts assisted by TEMPO (TEMPO = 2,2,6,6-tetramethyl-1-piperidine-N-oxyl) as the radical co-catalyst in the presence of atmospheric air under mild conditions is reported. The Cu-I-Y zeolite prepared via ion exchange between CuCl and HY zeolite was fully characterized by a variety of spectroscopic techniques including XRD, XPS, SEM, EDX and HRTEM. The incorporation of Cu(i) into the 3D-framework of the zeolite rendered the catalyst with good durability. The results of repetitive runs revealed that in the first three runs, there was hardly a decline in activity and a more substantial decrease in yield was observed afterwards, while the selectivity remained almost unchanged. The loss in activity was attributed to both the formation of CuO and the bleaching of copper into the liquid phase during the catalysis, of which the formation of CuO was believed to be the major contributor since the bleaching loss for each run was negligible (<2%). In this catalytic system, except TEMPO, no other additives were needed, either a base or a ligand, which was essential in some reported catalytic systems for the oxidation of alcohols. The aerobic oxidation proceeded under mild conditions (60 degrees C, and 18 hours) to quantitatively and selectively convert a wide range of benzylic alcohols to corresponding aldehydes, which shows great potential in developing green and environmentally benign catalysts for aerobic oxidation of alcohols. The system demonstrated excellent tolerance against electron-withdrawing groups on the phenyl ring of the alcohols and showed sensitivity to steric hindrance of the substrates, which is due to the confinement of the pores of the zeolite in which the oxidation occurred. Based on the mechanism reported in the literature for homogenous oxidation, a mechanism was analogously proposed for the aerobic oxidation of benzylic alcohols catalysed by this Cu(i)-containing zeolite catalyst.

Six heterobimetallic alkali metal dioxidovanadium(V) coordination polymer complexes {[M-6{VO(mu-O)}(2)(mu-OH)(4)(mu(4)-slox/nph)].n DMF}(infinity) where M = Na, K, and Cs; n = 1 for (1), 0 for (2)-(6) of two dihydrazone ligands, disalicylaldehydeoxaloyldihydrazone (H4slox) and bis(2-hydroxy-1-naphthaldehyde)oxaloyldihydrazone (H4nph) are reported. All the complexes have been characterized by various physicochemical techniques such as elemental analyses, molar conductance, IR, NMR, UV-vis, and cyclic voltammetry. The IR, (HNMR)-H-1, and (CNMR)-C-13 spectral data suggest that the dihydrazones are coordinated through phenolate/naphtholate oxygen, enolate oxygen, and azine nitrogen atoms to the metal centres. The structure of complex {[Na-6{VO(mu-O)}(2)(mu-OH)(4)(mu(4)-slox)].DMF}(infinity) (1) is also determined by single crystal X-ray data, which revealed that the H(4)slox coordinated via all possible dative sites to metal centres as tetrabasic octadentate ligand. The vanadium metal centres adopted distorted square-pyramidal coordination geometries, and the sodium atoms are also in five coordination atmospheres. The electronic spectra of the complexes showed LMCT bands in addition to intra-ligand pi -> pi* and n -> pi* transitions. As evident from the cyclic voltammetry, the complexes showed two metal centred electron transfer reactions {[((VVV)-V-V(slox)(2-)/(VVIV)-V-V(slox)(3-)] and [((VVIV)-V-V(slox)(3-)/(VVIV)-V-V(slox)(4-)]}, in addition to the ligand centred electron transfer reactions. Further, bovine serum albumin (BSA interaction studies of the complexes {[Na (6){VO(mu-O)} (2)(mu-OH) (4)(mu(4)-slox)].DMF} (infinity) (1) and [Na-6{VO(mu-O)}(2)(mu-OH)(4)(mu(4)nph)](infinity) (4) revealed strong binding affinity. Moreover, the catalytic studies of the complexes (1) and (4) were found to be effective for the oxidation of alcohols into their corresponding aldehydes and ketones and bromination of some organic substrates in the presence of H2O2 as an oxidizing agent.

Direct conversion of carboxylic acids to ureas, carbamates, and thiocarbamates in a single pot via Curtius rearrangement is accomplished. One recently established coupling reagent, Ethyl-2-cyano-2-(2-nitrophenylsulfonyloximino)acetate (ortho-NosylOXY, I), is successfully used for the racemization free synthesis of ureas, di-peptidyl ureas, and carbamates with moderate to good yield (82-69%). This single-pot hassle-free procedure works with a diverse range of N-protecting groups Fmoc, Boc, and Cbz. Various amine, including aromatic, methyl esters of amino acids, t-butylamine, alcohols, and thiols, are used as nucleophiles. A detailed NMR-based mechanism study is incorporated here. Racemization suppression, easy removal of by-products, and less waste generation make this methodology useful.

Though concept of oxygen bridged bimetallic catalyst for organic reaction is not well understood. Herein, we have tried to explain the concept by experimental as well as its support by full DFT study. We report here a competent protocol for dehydrogenative oxidation of benzylic alcohol using an oxygen bridged bimetallic CuMoO4 nano catalyst. Careful demonstration reveals that oxidation is not effective either with mono-metallic Cu (II) or Mo(VI); instead combination of both the metals through the oxygen bridge [Cu-O-Mo] unexpectedly and interestingly catalyzed the reaction efficiently. The new concept is strongly supported by computational DFT study. DFT study reveals dehydrogenative oxidation is preferred at copper centre over molybdenum and aromatic benzyl alcohols are greatly stabilised. Interaction barrier energy of monometallic CuO and MoO3 catalyst is much higher than bimetallic CuMoO4. Hydrogen transfer has larger barrier heights for CuO (31.5 kcal/mol) and MoO3 (40.3 kcal/mol) than bimetallic CuMoO4.

The traditional Staudinger/aza-Wittig reaction represents one of the most powerful tools for imine formation. However, for this multistep procedure, the sacrificial phosphine has to be used, resulting in difficulties in the purification process and waste disposal at the same time. Here, we report a redox-neutral azide-alcohol imination methodology enabled by a base-metal nickel PN3 pincer catalyst. The one-step, waste-free, and high atom-economical features highlight its advantages further. Moreover, mechanistic insight suggests a non-metal-ligand cooperation pathway based on the observation of an intermediate and density functional theory calculations.

Selective conversion of aromatic alcohols to value-added chemicals is becoming an emerging research hotspot in heterogeneous photocatalysis, but its critical challenge is how to construct highly efficient photocatalysts. Herein, mesoporous (001)-TiO2 nanocrystals with tailored Ti3+ and surface oxygen vacancies have been fabricated by a facile hydrothermal route, showing remarkably boosted photoactivity for selective conversion of aromatic alcohols to carbonyl compounds in water medium under visible-light irradiation. Results attest that the remarkably boosted photoactivity was mainly correlated with the strong synergetic effect of exposed (001) facets, Ti3+ self-doping, and surface oxygen vacancies, leading to the enhanced reactant (aromatic alcohols and O-2) activation via the high surface energy of (001) facets, the improved visible-light absorbance via the intrinsic band gap narrowing, and the escalated photoelectron-hole separation efficiency via Ti3+ and surface oxygen vacancies acting as electron sinks. Meanwhile, a plausible photocatalytic mechanism for selective conversion of aromatic alcohols to carbonyl compounds has been elucidated in detail based on active species identified by capture experiments. It is hoped that this work can deliver some new insights into the rational design of highly efficient photocatalysts applied in future green organic selective transformation reactions.
