A DIRECT ARYLSELENENYLATION OF ENONES WITH DIARYL DISELENIDES BY A ELECTROREDUCTIVE PROCEDURE
Torii, Sigeru,Inokuchi, Tsutomu,Hasegawa, Nobu
, p. 639 - 640 (1980)
A new procedure for arylselenenylation of enones has been developed by electrolysis with diaryl diselenide and chlorotrimethylsilane in methanol.In the course of the reaction generation of aryl selenols in situ is assumed.
