摘要

Previously, we reported the AlCl 3 -mediated heterolytic cleavage of the NO bond of N-phenoxybenzamides that leads to an intramolecular migration of the benzamido group from the oxygen to the ortho position of the phenyl ring. 4 In an extension of this work, we have investigated the reaction of O-arylketoximes (1) with Lewis acids in benzene. We now report that ZrCl 4 -mediated decomposition of 1 leads to an efficient electrophilic intramolecular migration of the imino group from the ...
