Abstract
Compounds of formula PnNnX2n, in which n is at least 3 and at least one X is a thiocyanate radical, are prepared by reacting PnNnX2n in which n is at least 3 and at least one X is halogen, in solution with an alkali metal or ammonium thiocyanate to replace halogen with -NCS. Any X which is not -NCS may be halogen or hydrocarbon. The thiocyanate is preferably that of potassium, and solvents are methyl cyanide or dimethyl formamide. Reference is made to producing [PN(NCS)2]3 and [PN(NCS)2]4 from the corresponding polymers of PNCl2 and P3N3(NCS)2(C6H5)4 and P4N4(NCS)2(C6H5)6 from P3N3Cl2(C6H5)4 and P4N4Cl2(C6H5)6 respectively. The lower polymers of the above general formula may be further polymerized by heating.ALSO:Novel compounds of formula PnNnX2n, in which n is at least 3 and at least one X is an isothiocyanate radical, are prepared by reacting PnNnX2n, in which n is at least 3 and at least one X is halogen, in solution with an alkali metal or ammonium thiocyanate to replace halogen with -NCS. Any X which is not -NCS is halogen or hydrocarbon. The thiocyanate is preferably that of potassium, and suitable solvents are methyl cyanide or dimethyl formamide.
