Reactions of azoalkenes derived from hydrazones of ethyl bromopyruvate with ele...
Clarke, S; Gilchrist, Thomas L.; Lemos, A.; G. Roberts, TonyThree hydrazones of ethyl bromopyruvate, the dinitrophenylhydrazone 2a, the toluene-4-sulphonylhydrazone 2b and the t-butoxycarbonylhydrazone 2c, have been reacted with a series of nucleophilic alkenes and heterocycles in the presence of sodium carbonate. Azoalkenes 3 are presumed as intermediates and adducts have been isolated. The azoalkenes derived from hydrazones 2a and 2c are found to be useful electrophil...
