Iron(iii)-catalyzed mono-, di- and tricyanomethylation of primary amines with diazoacetonitrile: construction of α-amino acetonitriles and asymmetric α-amino succinonitriles

Fe( iii )-catalyzed divergent synthesis between primary amines and diazoacetonitrile was reported. Mono- and dicyanomethylation are controlled by solvent, di- and tricyanomethylation represent a novel transformation in metalloradical catalysis field.
