Hemin Catalyzed Dealkylative Intercepted [2, 3]-Sigmatropic Rearrangement Reactions of Sulfonium Ylides with 2, 2, 2-Trifluorodiazoethane

A dealkylative intercepted [2, 3]-sigmatropic rearrangement reaction of allylic sulfides with 2, 2, 2-trifluorodiazoethane (CF3CHN2) is reported, the commercially available and biocompatible catalyst hemin was found to efficiently catalyze this transformation across a diverse set of allylic sulfides with in situ generated CF3CHN2, providing excellent yields (up to 99%) under mild condition without inert gas protection. In addition, CF3CHN2 exhibited unique reactivity toward this process compared with other frequently used diazo reagents. This work expands the range of carbene-mediated transformations catalyzed by hemin and introduces a concise and general strategy for exploiting new possibility of reactions concerning organosulfides.

Ruthenium-catalyzed decarboxylative C-S cross-coupling of carbonothioate: synthesis of allyl(aryl)sulfide

A novel ruthenium-catalyzed decarboxylative cross-coupling of carbonothioate is disclosed. This method provides straightforward access to the corresponding allyl(aryl)sulfide derivatives in generally good to excellent yields under mild conditions and feat

Synthesis of thioethers by ini3-catalyzed substitution of siloxy group using thiosilanes

The substitution of a siloxy group using thiosilanes smoothly occurred in the presence of InI3 catalyst to yield the corresponding thioethers. InI3was a specifically effective catalyst in this reaction system, while other typical Lew

Vanadium-catalyzed enantioselective oxidation of allyl sulfides

The enantioselective oxidation of allyl sulfides with a vanadyl complex of 3,5-diiodosalicylidene tert-leucinol as a catalyst and aqueous hydrogen peroxide as an oxidant afforded chiral allyl sulfoxides with high enantioselectivities of up to 97.3% ee and moderate yields.

Fast ruthenium-catalysed allylation of thiols by using allyl alcohols as substrates

The allylation of aromatic and aliphatic thiols, by using allyl alcohols as substrates, requires only minutes at ambient temperature with either a Ru Iv catalyst, [Ru(Cp*)(n3CH5)(CH 3CN)2](PF6)2 (2; Cp* = pentamethylcyclopentadienyl) or a combination of [Ru(Cp*)(CH 3CN)3](PF6) and camphor sulfonic acid. Quantitative conversion is normal and the catalyst possesses high functional-group tolerance. The use of [Ru(Cp*)(CH3CN) 3](PF6) alone affords poor results. A comparison is made to the results from catalytic runs based on the use of carbonates rather than alcohols, by using 2 as the catalyst, and it is shown that the products from the alcohols are formed faster, so there is no advantage in using a carbonate substrate. The observed branched-to-linear (b/1) ratios when using substituted alcohols decrease with time suggesting that the catalysts isomerise the products. A new methodology from which one can select the desired isomeric product is proposed. DFT calculations and NMR spectroscopic measurements, by using an arene sulfonic acid as co-catalyst, suggest that 6-complexes are not relevant for the catalytic system. Moreover, the DFT results indicate that l)any rf-complexes from the acids RC6H4SO 3H result from deprotonation of the acid, 2) complexation of the thiol, via the deprotonated sulfur atom, is preferred over complexation of the O atom of the sulfonate, RC6H4SO3and 3) a sulfonate O-atom complex will be difficult to detect.
