2-(Diphenylphosphino)-biphenyl Use and Manufacturing
General procedure: MCM-41-3N-Pd(0) (21mg, 0.01mmol), KOAc (1.5mmol) and aryl iodide 1 (1.0mmol) (if solid) were placed in an oven-dried 20mL Schlenk tube, the reaction vessel was evacuated and filled with argon for three times. Then aryl iodide 1 (1.0mmol) (if liquid), diphenylphosphine (1.2mmol) and DMAc (1mL) were added with a syringe under a counter flow of argon. The reaction mixture was stirred at 130°C for 3h. After completion of the reaction, the mixture was cooled to room temperature and diluted with CHGeneral procedure: In a sealed vial, under nitrogen, p-methylbenzoyldiphenylphosphine (61 CsGeneral procedure: MCM-41-3N-Pd(0) (21mg, 0.01mmol), KOAc (1.5mmol) and aryl iodide 1 (1.0mmol) (if solid) were placed in an oven-dried 20mL Schlenk tube, the reaction vessel was evacuated and filled with argon for three times. Then aryl iodide 1 (1.0mmol) (if liquid), diphenylphosphine (1.2mmol) and DMAc (1mL) were added with a syringe under a counter flow of argon. The reaction mixture was stirred at 130°C for 3h. After completion of the reaction, the mixture was cooled to room temperature and diluted with CH2Cl2 (20mL) and filtered. The MCM-41-3N-Pd(0) catalyst was washed with distilled water (2×5mL) and ethanol (2×5mL), and reused in the next run. The filtrate was concentrated in vacuo and the residue was purified by flash column chromatography on silica gel to provide the product 2.General procedure: To a solution of [Fe2(CO)6(m-SCH2CH2S)] (0.037 g, 0.1 mmol) and tris(4-methylphenyl)-phosphine (0.032 g, 0.1 mmol) in CH2Cl2 (5 mL) was added a solution of Me3NO2H2O(0.011 g, 0.1 mmol) in MeCN (5 mL). The mixture was stirred at room temperature for1 h and then the solvent was reduced on a rotary evaporator. The residue was subjectedto TLC using CH2Cl2/petroleum ether1:5 (v/v) as eluent. From the main redband, 0.054 g (83%) of 2 was obtained as a red solid.
