2-Acyl-2-bromoacetylenes react with dithiocarbamic acids in aprotic solvents (acetonitrile, chloroform, or ether) to give 5-acyl-2-diethylamino(heteryl)-1,3-dithiolium bromides, which on reaction with secondary amines (diethylamine or morpholine) undergo cleavage of the 1,3-dithiole ring to give 1-acyl-2-diethyl(morpholyl)dithiocarbamoyl-2-diethylamino(morpholyl)ethylenes. X-ray crystallographic studies on the product from one of these reactions has shown it to be 5-thenoyl-2-diethylamino-1,3-dithiolium bromide.
