Abstract
Complex formation of 9-phenyl-9-phosphafluorene with bis(acetylacetonato)palladium in benzene and acetonitrile was studied by means of NMR, IR, and UV spectroscopy. The structure of the resulting complexes, as well as specific features of catalytic oxidation of the arylphosphine and the reduction of Pd(II) to Pd(0) to form the complex Pd(PC1 8H1 3)4 were explored. 9-Phenyl-9-phosphafluorene gives two types of complexes with Pd(acac)2). The first ones are similar to triphenylphosphine complexes, and the others (π complexes) are formed by coordination of the planar aromatic π system of the phosphine to the plane of Pd(acac)2.
