有机金属催化剂（配体）。

{ALF} Chelating phosphorus ligand.

{ALD} Beilstein: 16,IV,958

{ALF} The complex with NiCl2 catalyzes the coupling of haloaromatic compounds with Grignard reagents: J. Org. Chem., 49, 478 (1984).

{ALF} Useful replacement for Triphenylphosphine, L02502, in the Staudinger and Mitsunobu reactions, with the advantage of easier separation of the by-product bis(phosphine oxide) due to its higher polarity compared with triphenylphosphine oxide: Tetrahedron Lett., 39, 7787 (1998). Has also been used as an alternative to PPh3 for the halodehydroxylation of alcohols, e.g. in combination with Hexachloroethane, L14297, alkyl chlorides are formed; the phosphine oxide by-product can readily be separated by filtration: Tetrahedron Lett., 42, 2459 (2001).

{ALF} The catalyst prepared in situ with Sodium tetrachloropalladate(II) hydrate, 11886, catalyzes the carbonylation of allylic halides at atmospheric pressure: Chem. Lett., 1873 (1989):
