investigated. These compounds were employed as bidentate anionic [P,O] ligands in neutral palladium complexes. The [P,O] chelating coordination was determined by X-ray crystallography of a representative palladium complex. Furthermore, the bifunctional ligand Ph(2)PC(6)H(4)PO(OH)Ph represents the first example of a chelating anionic [P,O] ligand resulting from the combination of a phosphine and a phosphinate
通往各种形式为Ar(2)PC(6)H(4)PO(OH)(2)(Ar = Ph,o-MeC(6)H(4),o- MeOC(6)H(4))已被研究。这些化合物在中性钯络合物中用作双齿阴离子[P,O]配体。通过代表性的钯配合物的X射线晶体学测定[P,O]螯合配位。此外,双功能配体Ph(2)PC(6)H(4)PO(OH)Ph代表由膦和次膦酸酯部分的组合产生的螯合阴离子[P,O]配体的第一个实例。
