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 80 C. and maintained at that temperature for 16.08 hours, then heated to 100 C. and maintained at that temperature for -0.97 hour. The salt is decanted and then vacuum dried. There is obtained 2.098 gms of an oily catalyst.
