For Heck reactions with bromobenzene and chlorobenzene it was found that the use of triethylamine and sodium carbonate increases the selectivity of the Heck coupling product (benzene is also produced for these two substrates), but the mixed bases do not affect the overall rate of reaction as much. Barcellos, José F. Cívicos, Pedro Merino, Carmen Nájera, Paulo R.R. In general, alkyl Heck reactions feature the same mech-anism as the classical Heck reaction between aryl halides and alkenes, involving: (1) oxidative addition, (2) migratory insertion, (3) β-hydrogen elimination, and (4) catalyst re-generation steps (Scheme 1). likely to decompose under the Heck reaction conditions.
