Nucleophilic Substitutions with Bischloronitroso Compounds. III. Reactions with Salts and Esters of the Dithiocarbazinic Acid and the N-Phenyldithiocarbazinic AcidBischloronitroso compounds 1 react with salts of the dithiocarbazinic acid to give S-(β-oximinoalkyl)-esters of the dithiocarbazinic acid. The esters easily cyclise to the corresponding 1,3,4-thiadiazine-2-thiones. Esters of the dithiocarbazinic acid lead to 2-alkylthio-1,3,4-thiadiazines. The structure of possible tautomeres follows from i.r.-, u.v./vis- and n.m.r.-spectra.
