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.

Anions of aliphatic nitro compounds R1R2C=NO2- react with nitroso compounds RNO to give nitrones R1R2C=N(O)R. Salts of nitro compounds with metals and Et3N, as well as trimethylsilyl nitronates in the presence of F-, can serve as the sources of the anions. The structure of the nitrones was established by NMR spectroscopy. 1,3-Dipolar cycloaddition of a series of the nitrones obtained to olefins was investigated.
