desulfurization-condensation reaction was investigated in the presence of silver(I) salt for several kinds of thiocarbonyl compounds with nucleophiles. Such thiocarbonyl compounds as 4,4′-bis(dimethylamino)thiobenzophenone, ethylene trithiocarbonate, and N-(thiobenzoyl)morpholine react with malononitrile or other active methylene compounds in the presence of silver trifluoroacetate to afford the corresponding
