91% With sodium tetrahydroborate; at 120℃; under 760.051 Torr; for 0.666667h;Microwave irradiation; Inert atmosphere; Green chemistry; 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 C for several hours. The light yellow complex was filtered in air and washed with 2×5 mL of petroleum ether/diethyl ether(1:1) mixture resulting in 580 mg of Mo(CO)4dppe after drying, a 95% yield.

YieldReaction ConditionsOperation in experiment
In diethylene glycol dimethyl ether; at 120℃; General procedure: Tetraethyl ammonium chloride (0.5 g) was heated with anexcess (1 g) of M(CO)6 (M = Cr, Mo, W) in diethylene glycol ether at 120 C until the steady evolution of carbon monoxide ceased. The mixture was filtered hot under an atmosphere of nitrogen. Adding light petroleum to the cooled filtrate gave yellow crystals of the product. After removal of the excessive solvent by decantation, the crystals were rapidly washed with light petroleum, and the excess of solvent was removed at reduced pressure.

65% In 1,3,5-trimethyl-benzene; for 2h;Reflux; Inert atmosphere; Schlenk technique; General procedure: 1a was prepared by a modification of the literature method [20,21]. [W(CO)6] (1.5g, 4.3mmol) and Me3tacn (950mg, 5.5mmol) were refluxed in mesitylene (25mL) for 2h under micro-negative pressure, and the reaction was accompanied by the release of CO gas. The reaction flask needs to be covered with a layer of cotton in case of the sublimation of [W(CO)6]. The solution was gradually cooled to room temperature, the yellow solid was filtered off, washed with hot toluene (2×5mL), ethanol (2×5mL), and diethyl ether (2×5mL), successively. The product was recrystallized in dichloromethane and light yellow needle crystals suitable for X-ray crystallographic analysis were collected in two days. Yield: 1.2g (65%). IR (KBr pellets, cm-1): nu(-CH3) 2945(m), nu(-CH2) 2913(m), 2861(s), nu(C?O) 1885(vs), 1750(vs), 1731(vs), nu(C-N) 1449(m). 1H NMR (400MHz, DMSO-d6): delta (ppm) 2.98 (s, 9H, -NCH3), 2.83~2.96 (m, 12H, -NCH2CH2).

The light yellow complex was filtered in air and washed with 2×5 mL of petroleum ether/diethyl ether(1:1) mixture resulting in 580 mg of Mo(CO)4dppe after drying, a 95% yield.

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 °C for several hours.
