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.

Indium-catalyzed direct preparation of dibenzyl sulfides from benzyl alcohols and elemental sulfur with a hydrosilane and its application to the preparation of dibenzyl selenide

We describe how a reducing system composed of InI3 and a hydrosilane efficiently and directly introduce elemental sulfur into the structure of dibenzyl sulfides via a nucleophilic substitution of benzyl alcohols. Also, we describe the application of this reducing system in the direct preparation of a dibenzyl selenide derivative with selenium.
