[Pd(η3-allyl)(η5-C5Me 5)] complexes react with tertiary phosphines and phosphites in a stepwise manner to give initially (η1-allyl)palladium complexes of the type [PdL(η1-allyl)(η5-C5Me5)]. Reaction with a second ligand molecule leads to transfer of a hydrogen atom from a ring-methyl group to the allyl group to give the (tetramethylfulvene)palladium(0) complex [PdL2(η2-CH2=C5Me4)]. The coordination of the fulvene molecule to the metal through the exo-methylene group has been established by an X-ray crystal structure determination of the trimethylphosphine adduct (space group P21/a, a = 12.139 (2) A?, b = 13.468 (2) A?, c = 12.294 (1) A?, β = 105.874 (8)°, Z = 4).
