PyroPhosphoryl tetramide

Pyrophosphoryl tetramide Is produced from pyrophosphoryl tetrachloride and NH 3 In chloroform solution ... 

Pyrophosphoryl tetramide, a colourless and odourless solid, can be made in 89% yield by reacting pyrophosphoryl chloride with liquid ammonia (7.73). If traces of water are present, the products (NH2)2P(0)0H, (NH2)2P(0)0NH4 and (NH2)3PO, and under other conditions some highly polymeric material can be formed (7.78). If the fluoride is used, the products are ammonium phosphorodifluo-ridate and aminodifluorophosphine oxide (7.74). The diammonium diamido salt is obtained from P4O10 and ammonia (4.50), or by hydrolysis of the tetramide (7.75). 

Pyrophosphoryl chloride is hydrolysed by water and it reacts readily with ammonia to give the tetramide (H2N)2P(0)0P(0)(NH2)2 and other products (Chapter 7). Polymeric (POjCOn can be prepared by the oxidation of PCI, with NjO. The mixed halide FC1P(0)0P(0)C1F can be obtained from POCljFandPAo.
