Kinetically stabilized 3-oxo-1,3-diphosphapropenes were prepared by oxidation of 1,3-diphosphapropenes with m-CPBA or from reaction of the corresponding phosphaethenyllithium with phosphinic chloride. The 3-oxo-1,3-diphosphapropenes were used as P,O-unsymmetrical bidentate ligands and the catalytic activity of the palladium(II) complexes in some cross-coupling reactions was investigated.
