Reaction of transition-metal complexes with hydroperoxides: oxidation of carbonyl, phosphine, and carbon ligands

Abstract

[Rh(CO)Cl(PPh₃)₂], [Ir(CO)Cl(PPh₃)₂], and [{Rh(CO)₂Cl}₂] react with Bu^tO₂H to give CO₂ in what appears to be a stoicheiometric reaction; with m-ClC₆H₄CO₃H the carbon-metal bond in [MCl(CH₂Ph)(PPh₃)₂](M = Pt or Pd) is cleaved to give m-ClC₆H₄CO₂CH₂Ph, and di-µ-chloro-bis{endo-η-2,3;η-5-(6-methoxybicyclo[2.2.1]hept-2-enept-2-enepalladium(II)} yields a methoxytricyclo[2.2.1.0]-heptyl m-chlorobenzoate.
