Procedure

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-tolyl phosphine and 24 gms of xylene. The slurry is heated to 45° C. then 2.7 gms (0.0197 mole) of 1-bromo butane is added. This reaction mass is heated to 50° C. and maintained at that temperature for 0.65 hour, then heated to 80C and maintained at that temperature for 16.08 hours, then heated to 100C and maintained at that temperature for -.97 hour. The salt is decanted and then vacuum dried. There is obtained 2.098 gms of an oily catalyst.
