Di-tert-butyl(2′,4′,6′-triisopropyl-3,4,5,6-tetramethyl-[1,1′-biphenyl]-2-yl)phosphine(CAT: L038606) is a sterically hindered, bulky phosphine ligand used primarily in organometallic chemistry and catalysis. The biphenyl backbone, combined with the bulky tert-butyl and triisopropyl substituents, provides substantial steric protection around the phosphorus atom, enhancing the ligand’s selectivity and stability in catalytic systems. This ligand is particularly useful in transition metal-catalyzed reactions, such as cross-coupling, hydrogenation, and C-H activation, where steric demands are beneficial. Di-tert-butyl(2′,4′,6′-triisopropyl-3,4,5,6-tetramethyl-[1,1′-biphenyl]-2-yl)phosphine is favored in the development of highly efficient, selective catalytic processes in both academic research and industrial applications.
