Synthesis method of dibenzyl sulfide

As an important organic intermediate and a synthesis reagent, an organic sulfur compound also has unique pharmacological effects of resisting tumors, inflammation, bacteria and oxidation, preventing aging, preventing and treating cardiovascular diseases and the like. The patent develops a method for synthesizing dibenzyl sulfide without metal catalysis. In an acetonitrile solution, benzyl trifluoromethanesulfonic acid quaternary ammonium salt and sodium sulfide nonahydrate are used to synthesize dibenzyl sulfide in a wide substrate range with good to excellent yield through breakage of a carbon-nitrogen bond and generation of a carbon-sulfur bond. The method has the advantages of mild reaction conditions, simple operation, no metal, high yield, wide substrate applicability and the like.

Alkyl Sulfides as Promising Sulfur Sources: Metal-Free Synthesis of Aryl Alkyl Sulfides and Dialkyl Sulfides by Transalkylation of Simple Sulfides with Alkyl Halides

A site-selective metal-free dealkylative approach to synthesize aryl alkyl and symmetrical dialkyl sulfides has been developed. This procedure is convenient and has wide functional group tolerance giving rise to sulfides carrying various alkyl chains from simple alkyl sulfides and alkyl halides in good to excellent yields. This transalkylation proceeds by an ionic mechanism via sulfonium intermediates and it was proposed that dimethylacetamide (DMAC) may participate in part to promote the reaction.

Indium-catalyzed reductive sulfidation of aromatic carboxylic acids and aldehydes with elemental sulfur to prepare symmetrical benzyl sulfides

Described herein is a direct approach to symmetrical thioethers from either aromatic carboxylic acids or aromatic aldehydes with elemental sulfur (S8) by using a reducing system combined with InI3 and 1,1,3,3-tetramethyldisiloxane (TMDS). This sulfidation does not require functionalized sulfur reagents, such as sulfides, disulfides, or metal sulfides, and it simultaneously forms two carbon-sulfur bonds in a single catalytic system. The coupling reaction of either aromatic carboxylic acids or aromatic aldehydes with elemental sulfur in the presence of a catalytic amount of InI3 and TMDS effectively produced the corresponding symmetrical benzyl sulfide derivatives.

Process for the preparation of trichloromethyl-substituted aromatic compounds, and trichloromethyl-substituted aromatic compounds obtained in this process

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.
