Contrary to a previous report, the sulfurisation of triphenylphosphines and trialkyl phosphites by 3-amino-1,2,4-dithiazole-5-thione (xanthane hydride) does not yield carbon disulfide and cyanamide as the additional reaction products but unstable thiocarbamoyl isothiocyanate which has been trapped with nucleophiles.
