✦ Synopsis

Lanthanum oxide/TMEDA-catalyzed cross-coupling of vinyl halides with thiols/diphenyl diselenide in anhydrous DMSO and KOH is reported. Utilizing this protocol various vinyl sulfides and selenides were synthesized in excellent yields with retention of the stereochemistry. The catalyst was recyclable.

The behaviour in acid media of hydroxy selenides and hydroxy sulfides (la-c and l'a-c) was investigated. The protection of the primary hydroxyl group in compounds la and l'a allowed the stereoselective synthesis of a substituted tetrahydrofuran ring, whereas compounds lb-c and l'b-c gave an efficien
