Reaction of the ferrocenylplatinum complexes trans-FcPt(PEt3)2 X (1) (Fc = ferrocenyl, X = Cl, Br, NCS) with 30 kg cm-2 of CO at room temperature leads to the insertion of CO into the Pt-C bond of 1 to give trans-FcC(O)Pt(PEt3)2 X (2) (X = Cl, Br, NCS) in good yield. Reactions of 1a (X = Cl) with an equimolar amount of aryl isocyanides produce the isocyanide insertion products trans-FcC(=NCAr)Pt(PEt3)2Cl (5) (Ar = p-MeC6H4, p-MeOC6H4, 2,6-Me2C6H3). In the reaction of 1a with p-nitrophenyl isocyanide, a mixture of cis and trans isomers was obtained in a 4: 1 ratio, while treatment with the other isocyanides gave only trans isomers. The structures of the insertion products were characterized by means of spectroscopic analyses and X-ray crystallography.
