The reaction of phosphorus tricyanide and sulphur dicyanide with sulphur chlorides

When an aqueous solution of N4P4(NH2)8 was refluxed at 100°C, the compound was initially hydrolyzed to PO(NH2)3 and P2O2NH(NH2)4, and they were converted into PO(ONa)(NH2)2. The rate of hydrolysis was remarkably slow at room temperature, however, the composition of the hydrolysis products was similar to that at 100°C. In a sosium hydroxide solution, N4P4(NH2)8 was converted directly into PO(ONa)(NH2)2 at an elevated temperature. An acid-hydrolysis behavior was resembled that in the neutral-hydrolysis, but the reaction was accelerated with an acid strength. The formation of tetrametaphosphimate by the hydrolysis of N4P4(NH2)8, that had been hitherto claimed, could not be recognized in this study.

Reaction of cis-NPCl2(NSOCl)2 with n-butylamine (molar ratio 1:2) in acetonitrile leads to a mono(amino) derivative, NPCl(NHBu) (NSOCl)2. Under the same experimental conditions sec-butylamine gives a mixture of about equal amounts of NPCl(NH-s-Bu) (NSOCl)2 and NPCl2NSOClNSO(NH-s-Bu), while tert-butylamine yields mainly NPCl2NSOClNSO(NH-t-Bu). The increasing tendency towards substitution at a sulfur atom can be ascribed to an increasing steric hindrance towards the formation of an 5N1 transition state with five coordinated phosphorus. The reaction of NPCl(NHBu) (NSOCl)2 with n-butylamine (molar ratio 1:2) gives a geminal bis(n-butylamino) derivative, which on fluorination yields NP(NHBu)2(NSOF)2. The 31P- and 19F NMR spectra of the compounds prepared are discussed.
