FLUORIDOLYSIS OF DIPHOSPHORYL COMPOUNDS

The behaviour of diphosphoryl compounds [X(2)(O)P]Y-2 in fluoridolysis reactions is decisively determined by the nature of the bridging grou p Y. In the cases of Y = NH and CH2 and X = Cl [F2P(O)]N-2(-) and [F2P (O)]2CH2 are obtained quantitatively. For Y = NPh, O, and CH2 the form ation of phosphorylated pentafluorophosphates [F5P-Y-POX(2)](-) is obs erved. Amido and ester derivatives containing fluorine (see table 2) a re obtained from the corresponding chloro compounds by Cl/F exchange. Fluoridolysis of the azadiphosphetidine 19 results in the formation of acyclic 19a.
