MECHANISM OF THE FORMATION OF PALLADIUM COMPLEXES SERVING AS CATALYSTS IN HYDROGENATION REACTIONS. II. REACTIVITY OF PALLADIUM PHOSPHINE HALIDES TOWARDS MOLECULAR HYDROGEN

Cl, benzene and aniline hydrochloride were isolated as products of the reactions of (PPh3)2PdCl2 or 2 with H2 in organic amines (Am).Similar products were obtained when (Ph3P)2Pd(Ph)Br was treated with H2 both in amines and aromatic solvents.The reaction between H2 and 2 resulted in the formation of 2*2Am.The kinetic data for H2 absorption by solutions of palladium(II) complexes are consistent with the heterolytic mechanism of cleavage of the H-H bond in the coordination sphere of palladium(II); the function of the H+ acceptor being performed by the bases (e.g.Am or Ph).The reaction between the palladium complexes and H2 is autocatalytic.Reduction of the initial PdII complexes leads to lower oxidation state palladium complexes, which catalyse the reduction of PdII complexes.In the coordination sphere of the lower oxidation state palladium complexes, the oxidative addition of PR3 to Pd takes place with formation of compounds containing a Pd-R bond.It is the reaction between these complexes and H2 that yields palladium compounds with PR2 ligands.
