Thiophosphoryl triamide

Thiophosphoryl triamide is prepared in a manner analogous to that of phosphoryl triamide, involving the reaction of ammonia with thiophosphoryl trichloride in chloroform while cooling 1... [Pg.111]

The crystals are colorless and rhombohedric. They are readily soluble in methanol and water, but insoluble in ethanol. When thiophosphoryl triamide is heated with sodium hydroxide, sodium diimidothiophosphate is formed ... [Pg.112]

Thiophosphoryl triamide must be stored in a sealed-off glass tube, f... [Pg.112]

I. Thiophosphoryl triamide is obtained similarly to phosphoryl triamide (see p. 584) via reaction of NH3 and PSCI3 in chloroform solution. The reaction flask must be well cooled (Klement and Koch) ... [Pg.587]

Amorphous polymeric materials with composition (PON) and (PSN) can be obtained from reactions of NHj with POCI3 and PSCI3, respectively. With more limited reactions, phosphoryl triamide or thiophosphoryl triamide (7.48) can be made. These compounds are colourless crystalline solids which are soluble in water, but the action of heat will eventually transform them into (PON) and (PSN) . The polymeric oxynitride can be made crystalline by heating to 700°C under pressure. [Pg.507]

Only salts of the thiophosphoramidic acids (9.543) have so far been isolated (9.544, 9.545). Thiophosphoryl triamide can be made by a reaction between ammonia and thiophosphoryl chloride inCH2Cl2at-50°C (7.48). [Pg.791]

Thiophosphoryl triamides, (R2N)3PS, are considerably more resistant to hydrolysis than their oxy counterparts, and the P-N bond is not attacked on heating with dilnte acids or alkalies. [Pg.792]
