, p. 8011 - 8013 (2007)
A general and easy method for the synthesis of several vinyl selenides using NaBH4 and BMIMBF4 as a recyclable solvent is described. This efficient and improved method furnishes the corresponding vinyl chalcogenides preferentially wi
Cerium(III)-mediated efficient and steroselective hydrochalcogenation of terminal alkynes

Vinylic chalcogenides were synthesized stereospecifically by hydrochalcogenation of propargylic amines or alcohols mediated by cerium(III) chloride. The products were obtained in good yields and with high regio- and stereoselectivities. Georg Thieme Verla

We present here the reaction of diphenyl dichalcogenides (Se and Te) with propargyl alcohols using alumina supported sodium borohydride under solvent-free conditions. This efficient and improved method is general and furnishes the corresponding vinyl chal
PREPARATION OF 3-HYDROXYL-VINYL SELENIDES AND 1,3-BIS(SELENO)-PROPENES
Renard, M.,Hevesi, L.
, p. 5939 - 5954 (2007/10/02)
Z and E 3-hydroxy-vinyl selenides can be prepared with very high stereoselectivity respectively by nucleophilic addition of selenolates to propargyl alcohols and by selenylation followed by LiAlH4 reduction of the same propargyl alcohols. 1,3-Bis(seleno)-
