2-Dicyclohexylphosphino-2′,6′-Dimethoxybiphenyl (Synonyms: SPhos) (CAS: 657408-07-6) is an air-stable, electron-rich biaryl phosphine ligand developed by the Buchwald group to enhance the reactivity of palladium catalysis during cross-coupling reactions. SPhos is a ligand used in chemical reactions for its ability to stabilize metal centers and increase reaction rates. SPhos was first developed by Professor Stephen Buchwald at the Massachusetts Institute of Technology in 2002 and was quickly adopted by chemists worldwide for its versatility.
SPhos (CAS: 657408-07-6) has low toxicity in various cell lines and does not pose significant safety concerns in scientific experiments. However, it is essential to handle SPhos with care as it can react with air and moisture, leading to a degradation of its chemical properties.
SPhos (CAS: 657408-07-6) has broad applications in scientific experiments, with its ability to stabilize metal centers and increase reaction rates. SPhos is commonly used in cross-coupling reactions, where it can aid in the formation of carbon-carbon and carbon-heteroatom bonds. SPhos has also been used in the development of pharmaceuticals and agrochemicals.
SPhos (CAS: 657408-07-6) has been used extensively in various chemical reactions and has been incorporated into many catalytic systems. SPhos has shown great potential in the development of new pharmaceuticals, and its use in cross-coupling reactions is still being explored.
