Title: Electronic effects in the reactions of coordinated isonitriles; bis-carbene complexes of platinum(II) and palladium(II)
Abstract: The reactions of complexes of the type cis-[PtCl2(RNC)(PR′3)] (R = p-CH3OC6H4, C6H5 or p-NO2C6H4; PR′3 = PPh3, PEtPh2, PEt2Ph or PEt3) with ethanol have been investigated. Reaction of the coordinated isonitrile with ethanol to give an ethoxy-carbene ligand is quickest for R = p-NO2C6H4 and slowest for R= p-MeOC6H4 consistent with nucleophilic attack at isonitrile carbon by ethanol. Variation of PR′3 has little effect on the reaction rate. The derived carbene complexes are characterised together with the bis-carbene complexes cis-[MCl2{C(OEt)NHp-NO2C6H4}2] (M = Pt or Pd) obtained by reaction of the cis-[MCl2(p-NO2C6H4NC)2] compounds with ethanol.
