Abstract
The thermal reactions of fluoroalkanesulfonyl azides RfSO2N3 with pyrazine and its derivatives are studied in detail. All the reactions involved the fluoroalkanesulfonyl nitrene intermediates RfSO3N: which was captured by pyrazine to give the pyrazinium N-fluoroalkanesulfonyl ylides C4NH4N+–−NSO2Rf and hydrogen abstraction product RfSO2NH2, but no corresponding N-pyrazinyl fluoroalkanesulfonyl amide derivatives RfSO2NHC4N2H3 were isolated. Excess azides did not afford the bisN-ylide product RfSO2N−–+NC4H4N+–−NSO2Rf.
