WebGreen Criteria for Suzuki Coupling Large molar excesses of reagents should be avoided if possible. Base metals should be used as catalysts in preference to Pd or other precious metals if possible. If Pd needs to be used, Pd/C (or other heterogeneous catalyst form) is preferred. Ligand-less reactions are preferred if possible.
