Addition of diethyl bromodifluoromethylphosphonate to various alkenes initiated by Co(III)/Zn bimetal redox system
Abstract
The addition of diethyl bromodifluoromethylphosphonate 1 to various alkenes 2 initiated by cobaloxime(III)/Zn bimetal redox system gives 1:1 Michael-type adducts 3 in moderate to good yields. A radical mechanism is proposed.
