We describe here a metal-free and selective method for the synthesis of (E)-1-bromo-1-seleno alkenes and ketene selenoacetals by a stoichiometric and temperature-controlled reaction. These protocols employ a diverse array of 1,1-dibromoalkenes and different diaryl diselenides to afford the corresponding products in good yields and in a short reaction time.

The substitution of bromine atom on a double bond by benzeneselenolate or benzenethiolate anions is catalyzed by the bis(pyridine)nickel bromide complex.Various alkenyl selenides or sulfides and seleno- or thio acetals are prepared in good to excellent yi
New synthetic routes to vinyl sulfides, ketene thioacetals and their seleno analogues from carbonyl compounds
Denis,Desauvage,Hevesi,Krief
, p. 4009 - 4012 (2007/10/02)
Title compounds have been prepared from carbonyl compounds by formal removal of hydroxyl and sulfenyl or hydroxyl and selenyl moieties from the corresponding functionalized β-hydroxysulfides or β-hydroxyselenides.
