In contrast to the diaryl, dialkyl, alkylaryl, and parent series, nothing is known about the generation and chemical behavior of arylbenzylnitrenium ions. Herein, we report that these species can be generated by a process involving an unprecedented therma

Substituent effects on the chemical shifts of the conjugation sites in α-phenyl-N-arylnitrones (2) have been investigated.Resonance effects predominate at these positions.The electronic effects of the substituents should be treated separately between electron-donating groups and electron-donating groups and electron-withdrawing ones.A plausible mechanism for the transmission of substituent effects in 2 has been proposed.
