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, are charge 5 gms (0.0164 mole) of tri-o-tolylphosphine and 23 gms of toluene. The slurry is heated to 27° C. then 3.08 gms (0.0197 mole) of ethyl iodide is added. This reaction mass is heated to 70° C. and maintained for 17 hours, then heated to 100° C. and maintained for 9 hours, then cooled to 70° C. and maintained for 15 hours, then cooled to 26° C. This mixture is filtered and washed with 6 gms of toluene. After vacuum drying, 1.6 gms of ethyltri(o-tolyl)phosphonium iodide is obtained which has a melting point of 247° C. to 250° C.
