This study rationally designed a heterogeneously catalyzed system (i.e., using Ni-Pd alloy nanoparticles supported on hydroxyapatite (Ni-Pd/HAP) under an H2atmosphere) achieving an efficient base-free formal C-S bond metathesis of various thiolsviasuppression of the Ni catalysis deactivation.

Reactions between arynes and alkyl sulfides have been extensively studied over the past few decades. These reactions commonly end with a dealkylation process and thus deliver thioethers as final products. In contrast, the transformation described furnishes valuable triarylsulfonium salts, in lieu of thioethers, from arynes and diarylsulfides. The reaction features mild conditions and a broad substrate scope. A suite of functional groups such as ketones, esters, nitriles, aryl ethers and aryl halides is tolerated, which can be issues faced by traditional synthetic methods. The practicality of the reaction and its extension to the synthesis of triphenyl selenonium salt are also exhibited herein.

Diaryl thioethers and S-cycles were obtained on the basis of the copper-catalyzed reaction of carbon disulfide and aryl iodides in the presence of DBU. This reaction enables the one-pot synthesis of diaryl thioethers by employing cheap, available, and easy-to-handle carbon disulfide with aryl iodides. The reaction was successfully employed in the construction of sulfur-containing cyclic molecules.
Process for the preparation of trichloromethyl-substituted aromatic compounds, and trichloromethyl-substituted aromatic compounds obtained in this process

, (2008/06/13)
Trichloromethyl-substituted aromatic compounds are obtained by the chlorination of thioethers of the formula STR1 wherein Ar represents an optionally substituted aryl radial, X1 denotes hydrogen or halogen, and R1 represents optionally substituted alkyl, aralkyl, the nitrile group, an optionally substituted aryl radical or the group STR2 wherein Ar and X have the meaning given. The compounds, of which some are new, can be used as intermediate products for plant protection agents.
