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
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.

The present invention relates to a reaction method comprising a step of supplying a liquid containing at least one raw material compound and a low-boiling compound having a standard boiling point lower than a standard boiling point of the raw material compound to a flow channel, a step of heating the liquid to produce a liquid reaction product and a gas component by a reaction of the raw material compound, and a step of separating a liquid phase containing the reaction product from a gas phase containing the gas component and the low-boiling compound.

A series of symmetrical and unsymmetricalbenzylthioethers have been synthesised using a onepot reaction frombenzylhalides and thiourea. This procedure avoids the isolation or handling of malodorous thiols and generates high yields of benzylthioethers in excellent purity.
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
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.
