Synthesis and Characterization of New BIS(Pentafluoroethyl)Phosphinic Acid Amides and Hydrazides. Crystal Structure of (C₂F₅)₂P(O)NH₂

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-NHCH₂C₆H_2-3,5-(t-C₄H₉)-4-OH was oxidized with PbO₂ to the corresponding oxo-radical.
