Phosphinites are organophosphorus compounds with the formula P(OR)R2. They are used as ligands in homogeneous catalysis and coordination chemistry.[1]
Skeletal formula of methyl diphenylphosphinite
Preparation[edit]
Phosphinites are prepared by alcoholysis of organophosphinous chlorides. For example, treatment of chlorodiphenylphosphine with methanol and base gives methyl diphenylphosphinite:
- ClPPh2 + CH3OH → CH3OPPh2 + HCl
Although they are esters of phosphinous acids (R2POH), phosphinites are not made via such intermediates.
