into the final products occur,viz., (1) the reactions of CS2 with primaryamines on heating (70–110 °C) yield mixed and symmetrical thioureas and the reactions of CS2 with secondaryamines give symmetrical dithiocarbamates, and (2) insertion of CS2 intoS-(thiocarbamoyl)thiohydroxylamines affords thiuram disulfides. Thiuram disulfides formed from primaryamines decompose to give isothiocyanates, which
