Li, Hai-Lou; Lian, Chen; Yang, Guo-Yu published the artcile< {Ti6}/{Ti10} Wheel Cluster Substituted Silicotungstate Aggregates>, HPLC of Formula: 699-12-7, the main research area is titanium tungstosilicate wheel preparation thioether oxidation catalyst; crystal structure titanium tungstosilicate wheel cluster.

Two novel Ti-oxo wheel cluster substituted silicotungstates (STs) [H2NMe2]9H9[Ti6O6(SiW10O37)3]·11H2O (1) and [H2NMe2]16H10[Ti10O11(SiW10O37)2(SiW9O35)2]·14H2O (2) were made by hydrothermal reactions. The polyoxoanion of 1 is a ring-shaped trimer where a Ti6O6 ({Ti6}) wheel cluster is encapsulated by three divacant [SiW10O37]10- (SiW10O37) fragments. However, 2 is built by two divacant SiW10O37 units and two rare trivacant [SiW9O35]12- (SiW9O35) fragments and further installs an unprecedented Ti10O11 ({Ti10}) double-wheel cluster. To the best of the authors’ knowledge, 2 is rare in POM chem. Studies on the catalytic oxidation properties reveal that 1 exhibits high catalytic activity toward the oxidation of various sulfides using H2O2 as an oxidant. Also, 1 can be facilely recycled and reused for at least five cycles without obvious loss of catalytic activity.

Ardakani, Mehdi Hatefi; Saeednia, Samira; Sabet, Mohammad published the artcile< Highly Efficient and Selective Oxidation of Sulfides to Sulfones with Hydrogen Peroxide Under Ultrasonic Irradiation Catalyzed by Copper(II) Schiff Base Complex Supported on Mesoporous MCM-41>, Recommanded Product: 2-(Phenylthio)ethanol, the main research area is sulfone sulfide selective oxidation hydrogen peroxide copper complex.

In this work, copper(II) Schiff base complex immobilized on functionalized mesoporous silica MCM-41 as a heterogeneous catalyst, MCM-41-pr-NH2-CuL, was successfully used to oxidize a range of sulfides with 30% hydrogen peroxide under ultrasonic irradiation The influence of different parameters namely solvent, catalyst amount, and kind of oxidant was investigated in order to find suitable reaction conditions. The obtained results demonstrated that this catalytic system was capable of catalyzing the selective oxidation of different sulfides to sulfones with 30% H2O2 under ultrasonic irradiation The related sulfones were acquired in good to excellent yields (67-98%) in this system. Furthermore, the results indicated that this work could be appropriate for chemo-selective oxidation of sulfides to sulfones in the presence of other functional groups. Simple filtration recovered this catalyst, and no significant loss in its catalytic activity and selectivity was observed after using for five times. Also, no critical alteration was recognized in the FT-IR spectrum of the recovered catalyst after using five times.

Mesoporous SBA-15 was synthesized and modified with 3-chloropropyltrimethoxysilane and then used in immobilization of creatinine groups, which were employed to introduce Y3+ and Ce3+ to give rise to two novel yttrium and cerium catalysts: SBA-15@Creatinine@M (M = Y and Ce). The structures of the SBA-15@Creatinine@M catalysts were determined using various techniques. These catalysts offered outstanding catalytic performances in the oxidation of sulfides to sulfoxides and in the preparation of 5-substituted 1H-tetrazoles. An important characteristic of the SBA-15@Creatinine@M catalysts is that they are very stable without a considerable decrease in their catalytic performance lasting seven cycles.

Porter, Ashlin G.; Hu, Hanfeng; Liu, Xuemei; Raghavan, Adharsh; Adhikari, Sarju; Hall, Derrick R.; Thompson, Dylan J.; Liu, Bin; Xia, Yu; Ren, Tong published the artcile< Heptamolybdate: a highly active sulfide oxygenation catalyst>, Application In Synthesis of 699-12-7, the main research area is crystal structure heptamolybdate preparation sulfide oxidation catalyst kinetics sulfone.

The sulfide oxygenation activities of both heptamolybdate ([Mo7O24]6-, [1]6-) and its peroxo adduct [Mo7O22(O2)2]6- ([2]6-) were examined in this contribution. [Mo7O22(O2)2]6- was prepared in a yield of 65% from (NH4)6[Mo7O24] (1a) upon treatment of 10 equiv of H2O2 and structurally identified through single crystal x-ray diffraction study. (Bu4N)6[Mo7O22(O2)2] (2b) is an efficient catalyst for the sequential oxygenation of Me Ph sulfide (MPS) by H2O2 to the corresponding sulfoxide and subsequently sulfone with a 100% utility of H2O2. Surprisingly, (Bu4N)6[Mo7O24] (1b) is a significantly faster catalyst than 2b for MPS oxygenation under identical conditions. The pseudo-first order kcat constants from initial rate kinetics are 54 M-1 s-1 and 19 M-1 s-1 for 1b and 2b, resp. Electrospray ionization mass spectrometry (ESI-MS) study of 1b under the catalytic reaction conditions revealed that [Mo2O11]2- is likely the main active species in sulfide oxygenation by H2O2.

Cinelli, Maris A.; Yang, Jun; Scharmen, Amy; Woodman, Joey; Karchalla, Lalitha M.; Stephen Lee, Kin Sing published the artcile< Enzymatic synthesis and chemical inversion provide both enantiomers of bioactive epoxydocosapentaenoic acids>, Quality Control of 699-12-7, the main research area is Enzymic synthesis epoxydocosapentaenoic acids Bacillus megaterium; chemoenzymatic synthesis; cytochrome P450; docosahexaenoic acid; epoxide inversion; epoxy fatty acids; lipids/chemistry; polyunsaturated fatty acids.

Epoxy PUFAs are endogenous cytochrome P 450 (P 450) metabolites of dietary PUFAs. Although these metabolites exert numerous biol. effects, attempts to study their complex biol. have been hampered by difficulty in obtaining the epoxides as pure regioisomers and enantiomers. To remedy this, we synthesized 19,20- and 16,17-epoxydocosapentaenoic acids (EDPs) (the two most abundant EDPs in vivo) by epoxidation of DHA with WT and the mutant (F87V) P 450 enzyme BM3 from Bacillus megaterium. WT epoxidation yielded a 4:1 mixture of 19,20:16,17-EDP exclusively as (S,R) enantiomers. Epoxidation with the mutant (F87V) yielded a 1.6:1 mixture of 19,20:16,17-EDP; the 19,20-EDP fraction was ∼9:1 (S,R):(R,S), but the 16,17-EDP was exclusively the (S,R) enantiomer. To access the (R,S) enantiomers of these EDPs, we used a short (four-step) chem. inversion sequence, which utilizes 2-(phenylthio)ethanol as the epoxide-opening nucleophile, followed by mesylation of the resulting alc., oxidation of the thioether moiety, and base-catalyzed elimination. This short synthesis cleanly converts the (S,R)-epoxide to the (R,S)-epoxide without loss of enantiopurity. This method, also applicable to eicosapentaenoic acid and arachidonic acid, provides a simple, cost-effective procedure for accessing larger amounts of these metabolites.

Immobilization of oxo-peroxo molybdenum(VI) species on natural biopolymer, chitosan led to the development of a new heterogeneous catalyst which displayed excellent activity, stability and chemoselectivity for the oxidation of a wide variety of sulfides to the resp. sulfoxides by H2O2 in water, at ambient temperature The catalyst has been comprehensively characterized by elemental anal., spectral studies (FTIR, Raman, solid-state 13C NMR and diffuse reflectance UV-Vis), PXRD, Brunauer-Emmett-Teller (BET), SEM, EDX and TGA-DTG anal. The d. functional theory (DFT) method has been employed to study the structure of the synthesized chitosan peroxomolybdenum complex (PMoCh). In addition to water, the catalyst is also highly compatible with a variety of safer organic solvents like methanol and acetonitrile. Apart from being high yielding and operationally simple, the developed catalytic protocol is environmentally clean and safe as it is absolutely free from halogenated organic solvent. Other significant green attributes of the methodol. include its ready scalability, high H2O2 efficiency and easy recyclability of the catalyst for several catalytic cycles with consistent activity/selectivity profile.

Anchoring of peroxotitanium (pTi) species to linear water-soluble acrylic acid based polymers, poly(sodium acrylate) (PA) and poly(sodium methacrylate) (PMA) led to the successful synthesis of a pair of new, water-tolerant and recyclable catalysts of the type [Ti2(O2)2O2(OH)2]4–L (L = PA or PMA), highly effective in chemoselective sulfoxidation of organic sulfides I (R = C6H5, Me, 4-MeC6H4, etc.; R’ = Me, C6H5, Bn, etc.) with 30% H2O2 in aqueous medium at ambient temperature The catalytic protocol is high yielding (TOF up to 11,280 h-1), operationally simple as well as environmentally clean and safe, being free from halide, or any other toxic auxiliaries. The catalysts are sufficiently stable to afford easy recyclability for at least 10 consecutive reaction cycles of sulfoxidation with consistent activity selectivity profile. Oxidation of dibenzothiophene (DBT) to resp. high purity sulfoxide or sulfone could also be accomplished using the same catalysts by variation of reaction conditions.
