A mixture of 0.0381 g CuI (0.2 mmol), 0.0464 g dpq (0.2 mmol) and 0.1077 g pop (0.2 mmol) were dissolved in the mixed solvents of 5 mL CH3OH and 5 mL CH2Cl2 at room temperature. The insoluble residues were removed by filtration, and the filtrate was evaporated slowly at room temperature for several days until yellow crystalline products have been obtained. Yield: 75%. Anal. Calc.for C50H36CuIN4OP2: C, 58.07; H, 4.31; N, 6.30.
