A solution of CuI (0.019 g, 0.1 mmol) in CH3CN(5 mL) wasadded to a stirred solution of 1,10-phenanthroline (0.018 g,0.1 mmol) and 2-(Dpp)bp (0.034 g, 0.1 mmol) in EtOAc(5 mL). The mixture was stirred for 5 min and then the precipitatewas filtered off. The resultant clear solution was setaside for evaporation in air. Orange block crystals of complex1 were obtained after 1 day and red crystals of complex2 were obtained the next day. These two different productswere separated manually under a microscope. Yield: 20.0 mg(28.2percent, based on Cu) for 1 and 24.4 mg (27.1percent, based onCu) for 2. Anal. Calc. for 1 C36H27N2P1Cu1I1:C, 60.98; H,3.81; N, 3.95. Found (percent): C, 61.04; H, 3.81; N, 3.88. IR(KBr pellet, cm?1): 3446sh, 3004s, 1789m, 1639m, 1550s,1448m, 1209w, 1120m, 716m; for 2 C36H27N2P1Cu2I2:C,48.07; H, 3.03; N, 3.12. Found (percent): C, 48.14; H, 3.04; N,3.04. IR (KBr pellet, cm?1): 3522sh, 3004s, 1639w, 1461m,1221s, 930s, 868s.
13885-09-1, 13885-09-1 2-(Diphenylphosphino)biphenyl 12976978, achiral-phosphine-ligands compound, is more and more widely used in various fields.
