Phosphine ligand
Chiral phosphine ligands in asymmetric synthesis. Molecular structure and absolute configuration of (1,5-cyclooctadiene)-(2S,3S)-2,3-bis(diphenylphosphino)butanerhodium(I) perchlorate tetrahydrofuran solvate

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.12150-46-8,1,1-Bis(diphenylphosphino)ferrocene,as a common compound, the synthetic route is as follows.

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.
