1 (0.332 g, 1.0 mmol) and CuI (0.191 g, 1.0 mmol) were dissolved in 5 ml CHCl3. After a few minutes, bq (0.257 g, 1.0 mmol) in 10 ml CHCl3 was added. The mixture was stirred at 40 C for 2 h. After this time, a burgundy solution was formed. Then the solvent was evaporated to dryness. A dark red solid was crystallized from CHCl3 to give microcrystals which are soluble in CHCl3, CH2Cl2, THF, DMSO, CH3CN and CO(CH3)2. Yield 52%. Anal. Calc. for C33H42CuIN5O3P: C, 50.94; H, 5.44; N, 9.00. Found: C, 50.78; H, 6.02; N, 8.91%. MS (CHCl3): 575.1 [Cu(bq)2]+ 100%, 319.0 [Cu(bq)]+ 13%, 650.2 [Cu(bq)1]+ 10%.
