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.

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.

Using a phase-vanishing (PV) system, hydrogen, oxygen, and hydrogen sulfide generated in situ from CaH2, KO2, and P2S5, respectively, were directly reacted with substances in the organic phase to afford the desired products. The selective synthesis of sulfides and disulfides was achieved with the evolution of H2S gas via tuning the bases used in the PV method. Using this PV system, reactions with hazardous gaseous reagents can be carried out easily and safely in a common test tube.
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.
Convenient and robust one-pot synthesis of symmetrical and unsymmetrical benzyl thioethers from benzyl halides using thiourea
Eccles, Kevin S.,Elcoate, Curtis J.,Lawrence, Simon E.,Maguire, Anita R.
experimental part, p. 216 - 228 (2010/10/03)
A series of symmetrical and unsymmetrical benzyl thioethers have been synthesised using a one-pot reaction from benzyl halides and thiourea. This procedure avoids the isolation or handling of malodorous thiols and generates high yields of benzyl thioether
