Sm/I2-mediated selective cleavage of the S-S or C-S bonds of sodium (Z)-allyl thiosulfates in aqueous media: Selective formation of di(Z-allyl) bisulfides or (2E)-methyl cinnamic esters

Selective cleavage of the S-S or C-S bonds in sodium (Z)-allyl thiosulfates in the presence of a Sm/I2-system was achieved to form the corresponding di(Z-allyl) disulfides or (2E)-methyl cinnamic esters in moderate to good yields in aqueous med

Mizoroki–Heck Cross-Coupling of Acrylate Derivatives with Aryl Halides Catalyzed by Palladate Pre-Catalysts

The Mizoroki–Heck (MH) reaction involving aryl halides with various acrylates and acrylamides has been studied using air and moisture-stable imidazolium-based palladate pre-catalysts. These pre-catalysts can be converted into Pd-NHC species (NHC = N-heterocyclic carbene) under catalytic conditions and are capable of facilitating the Mizoroki–Heck reaction of aryl halides with various acrylates. The effects of solvent, catalyst loading, temperature and bases on the reaction outcome have been investigated. Various coupling partners were tolerated under the optimal reaction conditions catalyzed by palladate 1, [SIPr·H][Pd(η3-2-Me-allyl)Cl2]. The efficiency of the optimized synthetic methodology was tested on various aryl halides and substituted acrylates as well as acrylamides. The MH reaction yielded the coupled products in good to excellent isolated yields (up to 98%).

Palladium(II) supported on polycarbosilane: Application as reusable catalyst for Heck reaction

Heck reaction catalyzed by palladium(II) attached polycarbosilane is reported. Polycarbosilane (PCS), which is an organic-inorganic hybrid polymer containing both Si and C in its back bone structure, was synthesized by the polycondensation of trichloromethylsilane and trimethoxyvinylsilane in the presence of sodium metal. Palladium acetate was attached to the polycarbosilane (Pd-PCS) and its catalytic activity was investigated. Heck reaction in which C-C coupling between aryl halides or vinyl halides and activated alkenes in the presence of a base has been selected for the study. Palladium ions supported on PCS have been used as a catalyst for the first time and it efficiently catalyzed Heck reaction and an yield of 75-90% was obtained with different substrates. For comparison, catalytic activities of Pd ions supported on SBA-15, activated charcoal and amorphous silica were also investigated. Results indicate the superior activity of Pd-PCS.
