13991-08-7, 1,2-Bis(diphenylphosphino)benzene is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of CuCl (19.6mg, 0.2mmol) and dppb (89.3mg, 0.2mmol) with an excess of batho (66.5mg, 0.2mmol) were dissolved in CH2Cl2 (5mL) and 17 CH3OH (5mL) solution, stirred at room temperature for 6h. The insoluble residues were removed by filtration, and the filtrate was evaporated slowly at room temperature to yield yellow crystalline products. Yield: 80%. Anal. Calc. for C54H40ClCuN2P2: C, 73.83; H, 4.59; N, 3.19. Found: C, 73.62; H, 4.73; N, 3.06%.
