Abstract
The present invention discloses new organic compounds (e.g., ligands), their metal complexes and compositions using those compounds. The invention also relates to the field of catalysis. In particular, this invention relates to new compounds which when combined with suitable metals or metal precursor compounds provide useful catalysts for various bond-forming reactions, including Suzuki cross-coupling reactions. The invention also relates to performing Suzuki cross coupling reactions with unreactive aryl-chlorides.
