Reaction Conditions

Reaction Steps

Into a 50 milliliter glass reactor equipped with a thermometer connected to a temperature controller, a heating mantle, a condenser and a magnetic stirring bar, is charged 5 gms (0.0164 mole) of tri-p-tolylphosphine and 23 gms of toluene. The slurry is heated to 35° C. then 4.3 gms (0.0177 mole) of benzyl iodide is added. This reaction mass is heated to 40° C. in 15 minutes and maintained for 16 hours then cooled to 26° C. and the resulting phosphonium salt collected by filtration, then vacuum dried. There is obtained 3.6 gms of catalyst which has a melting point of 210° C.-218° C. and a chemical shift of 28.5 ppm (phosphoric acid reference).
