Several α(dimethylamino)aldehyde hydrazones of the general structure 11 have been obtained by alkylation of the lithium salt of 9 or by addition of Grignard reagents to 15 or 17.The compounds react with acyl chlorides to give hydrazones of unsaturated aldehydes.The same products 27 are obtained by thermal degradation of the ammonium salts 26.In the hydrazonoammonium salts 26a, g the trimethylammonium group can be substituted by a variety of nucleophiles (--> 34-39).

(2-Alkoxyvinyl)diazenium salts 9 and 14 are obtained by O-alkylation of glyoxal- (4) and methylglyoxal monodimethylhydrazone (13), resp., with alkyl trifluoromethanesulfonates.Bromination of N-(trimethylsilyl)enehydrazines 16 and 18 in pentane leads to th
