Description
Used as a phosphine-free ligand in various metal-catalyzed coupling reactions, often with advantageous results in difficult cases. For use in the Pd-catalyzed cross-coupling of aryl Grignards with aryl chlorides (Kumada reaction). Many examples have been recorded of the use of NHC ligands in the Suzuki coupling reaction, for examples utilizing 1,3-dimesitylimidazol-2-ylidene, in the coupling of arylboronic acids with relatively unreactive aryl chlorides.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
