Hydroaminoalkylation of sterically hindered alkenes with N,N-dimethyl anilines using a scandium catalyst

An atom- and step-economical C(sp(3))-H addition of N,N-dimethyl anilines to various sterically demanding 1,1- and 1,2-disubstituted alkenes has been achieved by using a simple beta-diketiminato ligand supported scandium dialkyl complex in combination with a borate compound. The corresponding C(sp(3))-C(sp(3)) bond forming reaction occurs with excellent regioselectivities to give a variety of tertiary aromatic amines.
