The pyrolyses of <I>N</I>-acyl immonium salts of <I>S</I>,<I>S</I>′-dimethyl <I>N</I>-methyl- (II) and <I>N</I>-phenyl-iminodithiocarbonates (III) were studied. <I>N</I>-Methyl-immonium salt II gave <I>S</I>-methyl <I>N</I>-acyl-<I>N</I>-methyl-dithiocarbamate (V) at 100°C, but <I>N</I>-phenyl derivatives (III) gave phenyl isothiocyanate and <I>S</I>-methyl thiolbenzoate (VI) at 140°C. On the other hand, cyclic immonium salt, 2-(<I>N</I>-benzoyl-<I>N</I>-methyl)-1,3-dithiolanylium chloride (IV) gave 2-benzoylimino-1,3-dithiolane(VII) with elimination of <I>N</I>-methyl group at 200°C. It was found that <I>N</I>-acyldithiocarbamate V isolated was further decomposed to methyl isothiocyanate and thiolbenzoate at 200°C. Independent syntheses of <I>N</I>-acyldithiocarbamates V were performed on the reaction of <I>N</I>-monosubstituted dithiocarbamates and acyl chloride.
