of alkyl and carboxylate ligands between Cp*(PMe3)Ir complexes
and d8 Pt and Pd complexes is described. Studies on the
scope and kinetics of this reaction support a mechanism in which carboxylate
dissociation from the Pt or Pd center precedes alkyl transfer from
Ir. Subsequent reaction of the resulting Pt or Pd alkyl complex enables
functionalization of the hydrocarbyl ligands and suggests new opportunities
for catalytic, nondirected C–C and C–H bond functionalization
reactions.
