| 释义 |
Phosphinites are organophosphorus compounds with the formula P(OR)R2. They are used as ligands in homogeneous catalysis and coordination chemistry.[1] PreparationPhosphinites are prepared by alcoholysis of organophosphinous chlorides. For example, treatment of chlorodiphenylphosphine with methanol and base gives methyl diphenylphosphonite: ClPPh2 + CH3OH → CH3OPPh2 + HCl Although they are esters of phosphinous acids (R2POH), phosphinites are not made via such intermediates. ReactionsOxidation of phosphinites gives phosphinates: 2 P(OR)R2 + O2 → 2 OP(OR)R2 Phosphinites are ligands, giving derivatives similar to metal phosphine complexes. They are stronger pi-acceptors than typical phosphine ligands.[2] References1. ^D. E. C.
