AlCl3-mediated regioselective migration of a methoxy group of N-methoxy-N-phenylamides to the ortho position of the phenyl ring
Abstract
AlCl3-mediated decomposition of N-methoxy-N-phenylamides in dichloroethane leads to regioselective intramolecular migration of the methoxy group from the nitrogen to the ortho position of the phenyl ring via a tight ion pair intermediate.
