The reaction of 1-N,O,S-substituted 1-ethenethiolates with carbon bisulfide leads to the formation of cyclic adducts.The reaction rate decreases in the order N > O > S.In the case of the 1-N- and 1-S-substituted 1-ethenethiolates the reaction products are 5-N- and 5-S-substituted 1,2-dithiole-3-thiones.In the case of the 1-O-substituted 1-ethenethiolates the reaction goes further with the formation of 3,3'-spirobi(1,2-dithiole).The relation reaction rate constants for 1-N,N-dimethylamino-2H-, 1-N,N-dimethylamino-2-methyl-, and 1-N,N-dimethylamino-2-phenyl-1-ethenethiolates are 1, 4.2 and 10 respectively.
