General procedure for the synthesis of diphenyl-2-pyridylphosphine from 2-iodopyridine and diphenylphosphine: MCM-41-3N-Pd(0) (21 mg, 0.01 mmol), KOAc (1.5 mmol), and 2-iodopyridine (1.0 mmol, if solid) were placed in an oven-dried 20 mL Schlenk tube. The vessel was evacuated and displaced three times with argon. Subsequently, 2-iodopyridine (1.0 mmol, if liquid), diphenylphosphine (1.2 mmol) and DMAc (1 mL) were added by syringe under argon protection. The reaction mixture was stirred at 130 °C for 3 hours. After the reaction was completed, the mixture was cooled to room temperature, diluted with CH2Cl2 (20 mL) and filtered.The MCM-41-3N-Pd(0) catalyst was washed with distilled water (2 × 5 mL) and ethanol (2 × 5 mL) for next use. The filtrate was concentrated under vacuum and the residue was purified by fast column chromatography on silica gel to obtain the target product diphenyl-2-pyridylphosphine.
