Synthesis, Reactivity and Structural Properties of Trifluoromethylphosphoranides.

ABSTRACT: Phosphoranides are interesting hypervalent species which serve as model compounds for intermediates or transition states in nucleophilic substitution reactions at trivalent phosphorus substrates. Herein, the syntheses and properties of stable trifluoromethylphosphoranide salts are reported. [K(18-crown-6)][P(CF₃ )₄ ], [K(18-crown-6)][P(CF₃ )₃ F], and [NMe₄ ][P(CF₃ )₂ F₂ ] were obtained by treatment of trivalent precursors with sources of CF₃ ^- or F^- units. These [P(CF₃ )_4-n F_n ]^- (n=0-2) salts exhibit fluorinating (n=1-2) or trifluoromethylating (n=0) properties, which is disclosed by studying their reactivity towards selected
