Synthesis and Reaction of α(Dimethylamino)alkanal Dimethylhydrazones

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).

Reactions of Unsaturated Aldehyde Dimethylhydrazones with Electrophilic Reagents

Crotonaldehyde dimethylhydrazone (1) is substituted at C-3 by electrophiles such as chlorine, bromine, iodine, arylsulfenyl chloride, phenylsulfinyl chloride, and nitronium tetrafluoroborate to form the products 10a-c, 18a,b, 25, and 26.In contrast, from
