General procedure: Cu(I) complexes were synthesized by the following route: [Cu(CH3CN)4](PF6) (0.124g, 0.4mmol) and bis(2-(diphenylphosphanyl)phenyl ether (POP) (0.216g, 0.4mmol) reacted in dichloromethane (15mL) at 25C for 2h. Then, the corresponding ligand (0.4mmol) was dissolved in the degassed dichloromethane solution and injected into the mixed solution for 2h. The resulting mixture was filtered through a plug of Celite and concentrated to ca. 1mL. Addition of Et2O (10mL) to the filtrate afforded a pale yellow precipitate, which was collected and washed with Et2O. And the product was recrystallized with ethanol., 166330-10-5

General procedure: The reactions were run in a CEM Corp. MARS microwave fitted with a fiber optic temperature probe and a port on top for a reflux condenser.1 mmol of Mo(CO)6 and dppe (0.425 g, 1.1 mmol) were combined with 20 mL of 1-propanol in a two-neck 100 mL RB flask. To this mixture was added NaBH4 (0.128 g, 3.3 mmol). The flaskwas placed in themicrowave and a reflux condenser attached through a hole in the top of the microwave. The mixture was sparged with nitrogen. The mixture was heated under nitrogen at 400 W for 1.5 min to reach reflux temperature. Once the reflux temperature was reached the microwave power was reduced and the temperature maintained for 18 min. The mixture was cooled to room temperature and 2?4 mL of water was added to the reaction to dissolve excess NaBH4 and promote product precipitation. The reaction was cooled ?10 ¡ãC for several hours. The light yellow complex was filtered in air and washed with 2¡Á5 mL of petroleum ether/diethyl ether(1:1) mixture resulting in 580 mg of Mo(CO)4dppe after drying, a 95percent yield.
