Reactions of 1-[benzoyl(2-hetaroyl)]-2,2-dimethyhydrazines with 1,3-dibromopropyne in MeOH at 50degreesC afforded 2-phenyl(heteryl)-6-bromomethylidene-4,4-dimethyl-5H-1,3,4-oxadiazinium bromides. Reactions of 1-[benzoyl(2-hetaroyl)]-2,2-dimethyhydrazines with propargyl bromide and allyl bromide gave rise to 1,1-dimethyl-1-(2-propyn-l-yl)- and 1,1-dimethyl-1-(2-propen-1-yl)-2-benzoyl(hetaroyl)hydrazinium bromides. On treating these compounds with NaOH solution the corresponding imides were obtained.
