P sub(4) functionalization by hydrides: direct synthesis of P-H bonds

P sub(4) functionalization by hydrides: direct synthesis of P-H bonds

A direct method for white phosphorus functionalization by hydride sources is presented. Excess BH sub(4) super(-) in n-butylamine produces HP sub(4) super(-) as the major P-containing species. Reaction with LiBEt sub(3)H forms the borane-stabilized phosphanide Li(PH sub(2))(BEt sub(3)) sub(2), which...

Zusammenfassung:A direct method for white phosphorus functionalization by hydride sources is presented. Excess BH sub(4) super(-) in n-butylamine produces HP sub(4) super(-) as the major P-containing species. Reaction with LiBEt sub(3)H forms the borane-stabilized phosphanide Li(PH sub(2))(BEt sub(3)) sub(2), which may be used to synthesize various phosphines. Triethylborane may be replaced by BH sub(3), resulting in the formation of LiPH sub(2)(BH sub(3)) sub( 2).
