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