A method for highly selective anti-Markovnikov hydroamination of terminal alkenes involves hydroboration of the alkene followed by a novel electrophilic amination of the alkyl borane catalyzed by an NHC-Cu complex. Terminal alkenes are successfully transformed into tertiary alkyl amines in the presence of a variety of functional groups in very good yields ranging with excellent regioselectivity.
