| Abstract: | Summary Five supported heterogeneous Pd catalysts have been prepared, characterized and found to be active and selective in the Suzuki-Miyaura coupling of boronic acids, and aromatic iodo and bromo compounds to form the corresponding biaryls in high selectivities. Reaction conditions, namely, the solvent, base (triethylamine, Na2CO3, Cs2CO3) and tetrabutylammonium chloride as an additive are shown to have profound effects on catalyst performance. |
