Pd nanoparticles were generated in situ from PdCl2 in tetrabutylammonium fluoride (TBAF·3H2O). Butyl 3-p-tolylacrylate was synthesized by the reaction of 1-iodo-4-methylbenzene and butyl acrylate in the presence of nano-pd/TBAF as catalyst. The reaction was readily performed with good yield under mild conditions. Moreover, the catalytic system could be recovered and reused several times in the reaction. The structure of the product was characterized with NMR and MS spectra.
