Abstract
Several phenyl and naphthyl triflates undergo catalytic cross-methylation with the monomeric and dimeric dimethyl-aluminum, -gallium and -indium complexes 1a, 1b, 1c, 3a, 3b and 3c in the presence of either PdCl2(PPh3)2, Pd(PPh3)4 or Pd(binap)(OAc)2. 4-Bromophenyl triflate reacts selectively via the triflate function. Structural features of the substrate and the methylating agent, as well as the nature and quality of the palladium catalyst have a considerable influence on the cross-coupling process.
