Abstract
Previously unknown bis(pentafluoroethyl)phosphinyl amides and hydrazides have been prepared in good yields by the reaction of bis(pentafluoroethyl)phosphinyl chloride or tris(pentafluoroethyl)phosphine oxide with the corresponding primary amines or hydrazines. The crystal structure of (C2F5)2P(O)NH2 was determined. The compound (C2F5)2P(O)NH-NHCH2C6H2-3,5-(t-C4H9)-4-OH was oxidized with PbO2 to the corresponding oxo-radical.
