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.

SULFUR EXTRUSION FROM DISULFIDES BY CARBENES

The present invention relates to a method for preparing a compound T having a thioether group from a compound D having a disulfide group in the presence of a carbene.

Thioether-linked liquid crystal dimers and trimers: The twist-bend nematic phase

Systematic synthesis of thioether-linked dimers and trimers was carried out to reveal molecular designs for inducing mesophases and twist-bend nematic (NTB) phases. A five-fold approach based on molecular structural parameters including the ter

Indium-catalyzed direct conversion of dibenzyl ethers to dibenzyl sulfides using elemental sulfur and a hydrosilane and its application to the preparation of benzyl selenides

Described herein is a catalytic system composed of an indium(III) compound, a hydrosilane and an easily handled form of elemental sulfur (S8) that effectively and directly catalyzes the sulfidation of dibenzyl ethers to produce dibenzyl sulfides. This system could also be applied to selenium in a straightforward conversion to dibenzyl selenides.

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.

Dithiooxamide as an Effective Sulfur Surrogate for Odorless High-Yielding Carbon-Sulfur Bond Formation in Wet PEG200 as an Eco-Friendly, Safe, and Recoverable Solvent

In this study, we have employed dithiooxamide, a solid, odorless, and commercially available compound, as a sulfur surrogate for the preparation of dialkyl sulfides from available alkyl halides in high yields. This sulfur transfer agent was also used for a copper-catalyzed high-yielding preparation of diaryl sulfides from their available aryl halides and for the preparation of thia-Michael adducts in high yields. All the reactions were performed under odorless conditions in wet PEG200 (PEG = polyethylene glycol), which is an eco-friendly, safe, and recoverable solvent. The protocols were easily applicable to large-scale operation.

Efficient reduction of sulfoxides with NaHSO3 catalyzed by I2
