7650-91-1, Benzyldiphenylphosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
7650-91-1, Complex 2: Solid AgSCN (0.0718 g, 0.43 mmol) was added to the solution of benzyldiphenylphosphine (0.2376 g, 0.86 mmol) in acetonitrile(50 cm3). The reaction mixture was heated under reflux for 5.5 h. The solution was filtered hot and the solvent was reduced to 10 cm3 by means of evaporation. The solution was left to crystallise from which small white crystals were isolated (0.2446 g,78%), mp 81-83 C. The product obtained was recrystallised from acetonitrile (5 cm3), from which large clear cubic crystals were isolated.Anal. Calc. for C39H34AgNSP2CH3CN: C, 64.83; H, 4.91; N,3.69; S, 4.22.
