Abstract

A combination of a Ni-H precatalyst and excess Brĝnsted acid enables a deallylation of O- and N-allyl functional groups. Key steps are a Ni-catalyzed double-bond migration of the O- and N-allyl group followed by Brĝnsted acid induced O/N-C bond hydrolysis. This deprotection method tolerates a broad range of functional groups.
