XYLYL ISOCYANIDE PLATINUM AND PALLADIUM COMPLEXES

Article abstract of DOI:10.1016/0022-328X(83)87186-1

Bis(cycloocta-1,5-diene)platinum reacts with isopropyl isocyanide to give the trinuclear complex .A related palladium compound was prepared by treating either or with 2,6-dimethylphenyl isocyanide.Reactions of the cluster and its presumed palladium analogue with the olefins (NC)2C:C(CN)2, F2C:CFCl and (CN)2C:C(CF3)2, give the compounds (M=Pt, Pd) in which the metals are η²-bonded to the coordinated olefins.The compound reacts with F2C:CFBr and with F2C:CFCl to give the traans complexes (X=Br, Cl).Similar compounds (M=Pt, Pd), (L=MeO2CHC:CHCO2Me, <*>OCH:CHCO<*>) have also been prepared, and characterised.Two platinum complexes <2> and (CNC6H3-2,6-Me2)4> have been synthesized by treating the complex with HSiMePh2 and cyclopropenone, respectively.NMR and IR data for the new species are reported and discussed.
