In conclusion, we have developed a novel synthesis of -arylethylamines that uses MHAT catalysis to trigger aryl migration of N-arylsulfonyl allylanilines. This hydroarylation protocol uses completely unactivated substrates to yield a series of valuable -arylethylamines, including construction of products with high steric-hindrance at the ortho-positions of the aromatic ring. Indeed, computational analysis demonstrates the requirement of ortho-aryl substitution to favour ipso radical addition and overcome the competitive ortho-addition.
