Abstract
The present invention discloses new efficient processes for various bond forming reactions, including Suzuki reactions and aryl aminations. Organic compounds (e.g., ligands), their metal complexes and compositions using those compounds, provide useful catalysts. The invention also relates to performing Suzuki cross coupling reactions with unreactive aryl-chlorides.
