and ruthenium-free approaches to protectedallylicamines and alkyl nitriles under photoredox conditions are reported. An inexpensive organic dye, eosin Y, catalyzes coupling of Boc-protected potassium α-aminomethyltrifluoroborates with a variety of substituted alkenyl sulfones through an α-aminomethyl radical addition–elimination pathway. Allylic and homoallylic amines were formed in moderate yields
