New and mild allyl carbamate deprotection method catalyzed by electrogenerated nickel complexes

A Ni(II)-catalyzed electrochemical procedure for the simple and mild deprotection of allyl carbamates to the corresponding amines is described. The amines are obtained in yields of 40–99% and the method is compatible with several functional groups. Electrolyses are carried out in DMF or in THF in single-compartment cells in the presence of a consumable zinc anode.
