Direct synthesis of disulfides from alkyl halides using thiourea and CCl4 in glycerol

Abstract Dialkyl disulfides were obtained on the basis of the reaction of alkyl halides and thiourea in the presence of CCl4 and Et3N. This procedure enables the odorless and one-pot synthesis of disulfides by employing cheap, easy-to-handle and readily available reagents and substrates in wet glycerol.

Deoxygenation and Desulphuration Reactions of Lithium: Part V - Reaction of Sulphoxides with Lithium

Dialkyl and aralkyl sulphoxides are reduced to the corresponding sulphides in good yields by lithium in dimethoxyethane; however, the reaction of benzyl sulphoxides with lithium is more complex.
