Synthesis and Characterization of New BIS(Pentafluoroethyl)Phosphinic Acid Amides and Hydrazides. Crystal Structure of (C<sub>2</sub>F<sub>5</sub>)<sub>2</sub>P(O)NH<sub>2</sub>
GRAPHICAL ABSTRACT 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
