calculations were used to rationalize the substituent effects on the competition between the benzylic cleavage and the McLafferty reaction and to clarify the role of the distonic arenium ion-type intermediate formed by the γ-hydrogen-transfer step of the McLafferty reaction. The ipso-protonolysis of the benzyl residue giving rise to the loss of substituted benzenes specifically from most of the para-isomers
