A rhodium-catalyzed carbonylative transformation of alkyl halides under low pressure of CO has been developed. This robust catalyst system allows using phenols as the carbonylative coupling partner and, meanwhile, exhibits high functional group tolerance and good chemoselectivity. Substrates even with a large steric hindrance group or multiple reaction sites can be selectively converted into the desired products in good to excellent yields. A gram-scale experiment was performed and delivered an almost quant. amount of the product. Control experiments were performed as well, and a possible reaction mechanism is proposed.

A facile access to highly fused tetracyclic indeno-1,2-benzothiazines has been established via a Rh(III)-catalyzed C-H bond activation and intramol. annulation cascade between sulfoximides and all-carbon diazo indandiones. This strategy is characterized by the fact that the diazo coupling partners do not require preactivation, along with its high efficiency, broad substrate generality, and facile transformation. Particularly, the highly conjugated tetracyclic products demonstrate good optical properties and can easily enter cells to emit bright fluorescence for live cell imaging.

Zhou, Qingqing; Ye, Man; Ma, Wenbao; Li, Difan; Ding, Bingjie; Chen, Manyu; Yao, Yefeng; Gong, Xueqing; Hou, Zhenshan published the artcile< Ionic Liquid Stabilized Niobium Oxoclusters Catalyzing Oxidation of Sulfides with Exceptional Activity>, Quality Control of 699-12-7, the main research area is ionic liquid stabilized niobium oxocluster catalyzing oxidation sulfide activity; hydrogen peroxide; oxidation; oxoclusters; peroxoniobium species; sulfides.

We present here a new class of niobium oxoclusters that are stabilized effectively by carboxylate ionic liquids These functionalized ILs are designated as [TBA][LA], [TBA][PA], and [TBA][HPA] in this work, in which TBA represents tetrabutylammonium and LA, PA, and HPA refer to lactate, propionate, 3-hydroxypropionate anions, resp. The as-synthesized Nb oxoclusters have been characterized by use of elemental anal., NMR, IR, XRD, TGA, HRTEM. It was found that [TBA][LA]-stabilized Nb oxoclusters (Nb-OC@[TBA][LA]) are uniformly dispersed with an average particle size of 2-3 nm and afforded exceptionally high catalytic activity for the selective oxidation of various thioethers. The turnover number with Nb-OC@[TBA][LA] catalyst was over 56 000 at catalyst loading as low as 0.0033 mol % (1 ppm). Meantime, the catalyst also showed the high activity for the epoxidation of olefins and allylic alcs. by using only 0.065 mol % of catalyst (50 ppm). The characterization of 93Nb NMR spectra revealed that the Nb oxoclusters underwent structural transformation in the presence of H2O2 but regenerated to their initial state at the end of the reaction. In particular, the highly dispersed Nb oxoclusters can absorb a large amount of polar organic solvents and thus were swollen greatly, which exhibited “”pseudo”” liquid phase behavior, and enabled the substrate mols. to be highly accessible to the catalytic center of Nb oxocluster units.

An electrochem. protocol for the selective oxidation of sulfides RSR1 (R = Ph, 2-bromophenyl, pyridin-2-yl, etc.; R1 = Me, 3-hydroxypropyl, cyclohexyl, etc.) and e.g., dibenzothiophene to sulfoxides RS(O)R1 and dibenzothiophene sulfoxide has been developed in NaCl that plays a dual role: (1) as an electrolyte for the electrochem. transformations and (2) as a redox mediator to avoid oxidation of sensitive functional groups. Instead of a traditional oxidant, this methodol. utilized traceless electrons as an ideal oxidant using anodic oxidation to access sulfoxides in good to excellent yields at ambient temperature This metal-free electrochem. protocol is simple, environmentally friendly, and compatible with various sensitive functional groups using mixed acetone/water as the green solvent. Moreover, the cost-effective graphite felt electrodes can be reused up to ten times without loss of electrochem. activity. The methodol. could be easily conducted on a gram or even a decagram scale.

New heterogeneous catalysts comprising of peroxidoniobium(V) complexes immobilized on amino acid grafted cross-linked poly(styrene-divinylbenzene) resin was developed. Results of FTIR, Raman, NMR, XPS, XRD, EDX, SEM, BET, TGA, and elemental anal. confirmed the successful anchoring of triperoxidoniobium(V), [Nb(O2)3]- species to the host polymer via the pendant amino acid groups. The supported catalysts exhibited excellent performance in epoxidation of styrene and a range of cyclic and terpenic compounds under environmentally acceptable solvent-free condition, with aqueous H2O2 as oxidant. The catalytic protocols provided excellent conversion to the desired epoxide (up to 100%) with selectivity > 99%, TON as high as 1000, and high H2O2 utilization efficiency (92-97%). Moreover, the catalysts efficiently facilitated chemoselective solvent-free oxidation of a variety of thioethers to sulfones at room temperature Simple operational strategy, easy recyclability for multiple reaction cycles with the consistent activity-selectivity profile are the addnl. significant attributes of the developed catalytic processes.

Monticelli, Serena; Urban, Ernst; Langer, Thierry; Holzer, Wolfgang; Pace, Vittorio published the artcile< A Straightforward Homologation of Carbon Dioxide with Magnesium Carbenoids en Route to α-Halocarboxylic Acids>, Reference of 699-12-7, the main research area is halo carboxylic acid preparation green chem diastereoselective chemoselective; magnesium carbenoid chloro sulfoxide carbon dioxide nucleophilic addition; dihalo carboxylic acid preparation green chem chemoselective; dihalomethane magnesium carbenoid carbon dioxide nucleophilic addition.

The homologation of carbon dioxide with stable, (enantiopure) magnesium carbenoids constitutes a valuable method for preparing α-halo acid derivatives RR1C(COOH)Cl (R = H, Et, 2,6-dimethylbenzyl, thiophen-2-ylmethyl, etc.; RR1 = -(CH2)2-; X = Cl, Br, I), 2-chloroacrylic acid and α, α-dihalo carboxylic acids XCH(Y)COOH (X = Cl, Br, I; Y = Cl, Br, I). The tactic features a high level of chemocontrol, thus enabling the synthesis of variously functionalized analogs. such as 1-chloro-2-(methoxycarbonyl)-2-methylcyclopropanecarboxylic acid and 1-chloro-2-methyl-1,2-cyclopropanedicarboxylic acid. The flexibility to generate magnesium carbenoids through sulfoxide-, halogen- or proton- Mg exchange accounts for the wide scope of the reaction.
