Iminodithiocarbonic acid esters. Phenyl isocyanide dichloride heated 7 hrs. at 110° with dimethylthallium thiophenoxide in toluene diphenyl N-phenyldithio-carbonimidate. Y 88.6%. F. e., also replacement of one Cl-atom and stepwise replacement by 2 different functions, s. B. Walther and W. Kolbe, Z. Chem. 13, 192 (1973). 

Synthesis of 1,3-selcnazole derivatives has been achieved by reactions of dimethyl A -(ethoxycarbonylmethyl)iminodithio-carbonate with selenothioethanoic acid 3 -ester < 1997JA8592>. Nucleophilic attack of the carbanion derived from dimethyl A -(ethoxycarbonylmethyl)iminodithiocarbonate at the C=Se group, followed by the elimination of -butyl thiolate, affords an intermediate which forms the selenazole by intermolecular nucleophilic attack (Scheme 11) <2003NJC1622>.
