Procedure

The vinyl triphenyl silane was reacted with 10% excess of diphenyl phosphine. To maintain a homogeneous reaction mixture, a temperature of 80° C. and cyclohexane solvent ere employed. After the usual u.v. initiated addition, the reaction mixture was allowed to cool to room temperature. This resulted in the crystallization of the triphenylsilyethyl diphenyl phosphine adduct. To obtain it in a pure form, the adduct was filtered and recrystallized from a four to one mixture of cyclohexane and toluene. A white crystalline product having a melting point of 128°-131° C. was obtained.
