Abstract

A direct method for white phosphorus functionalization by hydride sources is presented. Excess BH₄⁻ in n-butylamine produces HP₄⁻ as the major P-containing species. Reaction with LiBEt₃H forms the borane-stabilized phosphanide Li(PH₂)(BEt₃)₂, which may be used to synthesize various phosphines. Triethylborane may be replaced by BH₃, resulting in the formation of LiPH₂(BH₃)₂.
