About the Preparation and Chlorination of Carbonyl Diisothiocyanate

An improved preparation of carbonyl diisothiocyanate (1) is described.Compound 1 can be stored in form of its stable hydrochloride 3.Depending on the reaction conditions chlorination of 1 leads to the acyl isocyanide dichlorides 5 or 8.Compound 5 reacts with amines to give: the triazines 9a - c, the ammelines 11a, b, the guanidines 12 and 16a, or the acylcarbodiimides 14 and 15.With sodium phenolate 5 forms the dialkylidene urea 17, and with thiolates the derivatives 18a - c of dithiocarbonic acid.Compound 8 racts with thiophenolate to give 19 and with tert-butylamine to yield the carbamoylcarbodiimide 20.
