Abstract

The Heck reaction of iodobenzene and methyl acrylate took place smoothly in NMP at 140 °C in the presence of 1 mol ppb of the pincer palladium complex [4‐tert‐butyl‐2,6‐bis{(3__R__,7a__S__)‐2‐phenylhexahydro‐1__H__‐pyrrolo[1,2‐c]imidazole‐1‐on‐3‐yl}phenyl]chloropalladium to give methyl cinnamate which corresponds to 520×10^6^ TON and 6500/sec TOF.
