The Heck reaction of iodobenzene and methyl acrylate took place smoothly in NMP at 140degreesC in the presence of 1 mol ppb of the pincer palladium complex [4-tert-butyl-2,6-bis((3R,7aS)-2-phenylhexahydro-1H-pyrrolo[1,2-c]imidazole-1-on-3-yl]-phenyl]chloropalladium to give methyl cinnamate which corresponds to 520 x 10(6) TON and 6500/sec TOF.
