The ring-opening of epoxides is a synthetically significant process widely applied in all kinds of chemistry. Herein, we report the catalytic and highly enantioselective variant of this reaction exploiting our recent endeavors to design and synthesize chiral bipyridine type ligands. A Sc-complex with a newly developed bipyridine ligand exhibited high reactivity and stereocontrol in the desymmetrization of meso-epoxides with various alcohols. The respective enantiomerically enriched 1,2-alkoxyalcohols were obtained with e.r. values of up to 99.5:0.5 for various alcohols regardless of their nature (benzyl, alkyl, cycloalkyl, allyl, propargyl, etc.). We attempted ring-opening of meso-epoxides with anilines as well; however, it proceeded with lower enantioselectivity and was strongly depended on the electronic effect of substituents attached to the aromatic ring.

Two copper(II) complexes [Cu-2(L-1)(2)] (1) and [Cu-2(L-2)(2)] (2) where H2L1=2-hydroxy-3-((3-hydroxy-2,2-dimethylpropylimino)methyl)-5-methylbenzaldehyde and H2L2=2-hydroxy-3-(((1-hydroxypropan-2-yl)imino)methyl)-5-methylbenzaldehyde have been synthesized and used as catalysts in alcohol oxidation. 2,6-Diformyl-4-methylphenol (DFP) based Schiff-base ligands, 3,3 ‘-(2-hydroxy-5-methyl-1,3-phenylene)bis(methan-1-yl-1-ylidene)bis(azan-1-yl-1-ylidene)bis(2,2-dimethylpropan-1-ol) (H3L ‘) and 2,2 ‘-(((2-hydroxy-5-methyl-1,3-phenylene)bis(methanylylidene))bis(azanylylidene))bis(propan-1-ol) (H3L ”), undergo partial hydrolysis to convert one of the azomethine groups to aldehyde group to give H2L1 and H2L2, and then react with copper(II) acetate to yield complex 1 and 2, respectively. These complexes have been characterized by standard methods such as elemental analysis, room temperature magnetic studies, FT-IR, UV-vis, ESI-mass spectral analyses, cyclic voltammogram, etc. The structures of dinuclear complexes with modified ligands have been confirmed by single crystal X-ray diffraction analysis. Complex 1 and 2 have been used as catalysts for the oxidation of benzyl alcohol, 4-methyl benzyl alcohol, 4-methoxy benzyl alcohol, 4-nitro benzyl alcohol and 4-bromo benzyl alcohol to the corresponding aldehyde as the sole product. Efficiency of the catalyst depends on the chain length and substitution on the chain of the ligand.

Arylation of carbonyls, one of the most common approaches toward alcohols, has received tremendous attention, as alcohols are important feedstocks and building blocks in organic synthesis. Despite great progress, there is still a great gap to develop an ideal arylation method featuring mild conditions, good functional group tolerance, and readily available starting materials. We now show that electrochemical arylation can fill the gap. By taking advantage of synthetic electrochemistry, commercially available aldehydes (ketones) and benzylic alcohols can be readily arylated to provide a general and scalable access to structurally diverse alcohols (97 examples, >10 gram-scale). More importantly, convergent paired electrolysis, the ideal but challenging electrochemical technology, was employed to transform low-value alcohols into more useful alcohols. Detailed mechanism study suggests that two plausible pathways are involved in the redox neutral alpha-arylation of benzylic alcohols.

N-doped TiO2, denoted as T_400, was prepared simply by the facile thermal hydrolysis of TiOSO4 using NH4OH as both a precipitating agent and a nitrogen source. Compared to TiO2 without nitrogen doping, T_400 provides superior photocatalytic activity toward the selective oxidation of benzyl alcohol and benzylamine under visible light irradiation, with > 85 % conversion and > 95 % selectivity to benzaldehyde and N-benzylidenebenzylamine products, respectively. The increased photoactivity of T_400 is ascribed to enhanced visible-light absorption and efficient photogenerated charge transfer and separation as supported by UV-vis DRS, photoelectrochemical and VB-XPS results. The catalyst can tolerate the presence of substituent groups in benzyl alcohol and benzelamine molecules as > 80 % conversion and > 95 % selectivity are still achieved, which expands the scope of substrates and catalyst utilization. Band energy level of N-doped TiO2 compared to that of undoped TiO2 is determined using Mott-Schottky and UV-vis DRS measurements. Possible mechanisms for the formation of benzaldehyde and N-benzylidenebenzylamine over N-doped TiO2 are proposed. This work presents a simple synthesis of N-doped TiO2, using a low-cost and easily handled inorganic titanium salt instead of air/moisture-sensitive alkoxide precursors and reveals its potential application toward photocatalytic synthesis of organic fine chemicals under visible light.

Direct oxidative coupling of alcohols with amines using a non-precious metal oxide catalyst under mild conditions is highly desirable for imine synthesis. In this work, a mesoporous Mn1ZrxOy solid solution catalyst prepared by a co-precipitation method showed excellent catalytic performance in imine synthesis from primary alcohols and amines without base additives in an air atmosphere. XRD, N-2 physisorption, H-2-TPR, O-2-TPD, EPR and XPS were comprehensively used to unravel its structural, redox and amphoteric properties that closely depended on the interaction between MnOy and ZrO2 with a variable Zr ratio. The Mn1Zr0.5Oy catalyst presented the highest fractions of Mn3+ ions and reactive oxygen species on the surface, and the highest concentrations of acidic-basic sites, which were disclosed to play important roles in activating alcohols and molecular O-2 in the rate-determining step. In the model reaction of oxidative coupling of benzyl alcohol with aniline, such enhanced features of the Mn1Zr0.5Oy catalyst can promote the intrinsic catalytic activity (iTOF of 1.87 h(-1)) and boost benzylideneaniline formation (5.56 mmol g(cat).(-1) h(-1)) based on a >99% yield at 80 degrees C respectively at a fast response. It can also work effectively at a room temperature of 30 degrees C, as well as for the gram-grade synthesis. This is one of the best results among all the MnOy-based catalysts in the literature. Moreover, this catalyst showed good stability and a wide substrate scope with good to excellent yields of imines.

The first examples of an iron-catalyzed three-component synthesis of homoallylic boronates from regioselective union of bis(pinacolato)diboron, an alkenyl halide (bromide, chloride or fluoride), and an olefin are disclosed. Products that bear tertiary or quaternary carbon centers could be generated in up to 87 % yield as single regioisomers with complete retention of the olefin stereochemistry. With cyclopropylidene-containing substrates, ring cleavage leading to trisubstituted E-alkenylboronates were selectively obtained. Mechanistic studies revealed reaction attributes that are distinct from previously reported alkene carboboration pathways.

The binary hydride, diisobutylaluminum borohydride [(iBu)(2)AlBH4], synthesized from diisobutylaluminum hydride (DIBAL) and borane dimethyl sulfide (BMS) has shown great potential in reducing a variety of organic functional groups. This unique binary hydride, (iBu)(2)AlBH4, is readily synthesized, versatile, and simple to use. Aldehydes, ketones, esters, and epoxides are reduced very fast to the corresponding alcohols in essentially quantitative yields. This binary hydride can reduce tertiary amides rapidly to the corresponding amines at 25 degrees C in an efficient manner. Furthermore, nitriles are converted into the corresponding amines in essentially quantitative yields. These reactions occur under ambient conditions and are completed in an hour or less. The reduction products are isolated through a simple acid-base extraction and without the use of column chromatography. Further investigation showed that (iBu)(2)AlBH4 has potential to be a selective hydride donor as shown through a series of competitive reactions. Similarities and differences between (iBu)(2)AlBH4, DIBAL, and BMS are discussed.

A dehydrogenative coupling of N-uracil amidines with (hetero)aryl methanols has been developed, allowing for the facile synthesis of a broad range of structurally diverse pyrimidouracils. By applying [RuCl2(p-cymene)](2)/Cs2CO3 as an efficient catalytic system, the easily available, cheap (hetero)aryl methanols were firstly employed for oxidative insertion/C-H amination into the N-uracil amidines, providing highly functionalized pyrimido[4,5-d]pyrimidine-2,4-diones. Due to the better stability of alcohols than aldehydes, this synthetic protocol is applicable to a broad range of alcoholic substrates and does not required any protection during the whole preparation process. The presented protocol has the potential to prepare valuable products which cannot be accessed presently or extremely arduous to procure by following regular procedure. Hence, this is a remarkably improved protocol compared with the existing methodologies. The overall reaction sequence is an effective oxidation-imination-cyclization tandem process catalyzed by ruthenium catalyst.

The novel free radical-based cleavage of the enaminone C=C double bond is realized by using N-halosuccinimides (NXS) in the presence of benzoyl peroxide (BPO) with mild heating, enabling the tunable synthesis of alpha,alpha-dihalomethyl ketones and alpha,alpha,alpha-trihalomethyl ketones under different reaction conditions. The formation of these divergent products involving featured C=C double bond cleavage requires no any metal reagent, and represents one more practical example on the synthesis of poly halogenated methyl ketones via the functionalization of carbon-carbon bond.
