The synthesis of the title compounds 3 (R(1) = R(2) = C2H5; n-C4H9) by reactions of N-(N',N'diethylthiocarbamoyl)benzimidechloride (2) with sodiumdialkyldithiocarbamates (1) in acetone is described. The low yields (< 25%) are caused by the occurrence of side reactions. The structures of the compounds were confirmed by IR, H-1 and C-13 NMR, and mass spectroscopy. Side reactions were detected by (13)CNMR spectroscopy; the results are discussed.
