WebLa groupe amino de ce phosphinite agit comme piège et permet d’enlever l’acide qui est produit. Une filtration simple permet d’enlever la phosphinate obtenu comme sous-produit. Mots clés... In organic chemistry, phosphinites are organophosphorus compounds with the formula P(OR)R2. They are used as ligands in homogeneous catalysis and coordination chemistry. See more Phosphinites are prepared by alcoholysis of organophosphinous chlorides. For example, treatment of chlorodiphenylphosphine with methanol and base gives methyl diphenylphosphinite: See more Oxidation 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 … See more • Phosphine - PR3 • Phosphine oxide - OPR3 • Phosphonite - P(OR)2R • Phosphite - P(OR)3 • Phosphinate - OP(OR)R2 See more
