A NOVEL GENERAL-METHOD FOR THE SYNTHESIS OF NITRONES BY REACTION OF NITROSO-COMPOUNDS WITH ANIONS OF ALIPHATIC NITRO-COMPOUNDS

Anions of aliphatic nitro compounds R(1)R(2)C=NO2- react with nitroso compounds RNO to give nitrones R(1)R(2)C=N(O)R. Salts of nitro compoun ds with metals and Et(3)N, 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 cycl oaddition of a series of the nitrones obtained to olefins was investig ated.
