240417-00-9, 2-Diphenylphosphino-2′-(N,N-dimethylamino)biphenyl is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
CH2Cl2 (25 ml) was added to a Schlenk flask containing the 2-(N,N-dimethlamino)-2′-(diphenylphosphino)biphenyl (2.00 g, 5.2 mmol) and (DME)NiBr2 (1.30 g, 4.2 mmol) in a dry box. A green solution formed immediately upon mixing. This solution was stirred for 20 hours. Then, it was filtered and recrystallized from CH2Cl2/pentane. The product was washed three times with an additional 15 ml of pentane and dried for 1 hour under vacuum. A green powder was isolated in 69.3% yield. The product was soluble in CH2Cl2. 1H NMR indicates that it is paramagnetic. Anal. Calcd for (C26H24NPBr2Ni) : C, 52.03% ; H, 4.08% ; N, 2.33% ; P, 5.16%. Found: C, 1.20% ; H, 4.24% ; N, 2.14% ; P, 5.29%.
