N-(Substituted formyl)dialkylamino(thioxo)methanesulfenamides (R2NCSSNHCOR', 2), anti-foggants for silver halide photographic materials as well as potential precursors for 1,4,2-dithiazolium salts, were prepared in good yields in two ''one-pot'' procedures.Various amide-type compounds (R'CONH2, 1) were treated successively with NaH and I2 and then condensed with dialkylditiocarbamates (Method A); or 1 were reacted with tetraalkylthiuram disulfides after treatment with NaH (Method B).These methods allowed a wide variation of substituents R' in 2: R' = H, dialkylamino, alkoxy, aryl, alkyl, and heterocyclic substituent.

N-(Dialkylthiocarbamoylthio)arenecarboxamides, prepared by acylation of the corresponding S-dialkylthiocarbamoyl-substituted sulfenamides, cyclized with dehydration in a strong acidic media to form a number of 3-aryl-5-dialkylamino-1,4,2-dithiazol-1-ium s
