Diallyldimethylsilane → [(Dimethylsilanediyl)di(propane-3,1-diyl)]bis(diphenylphosphane)

Participants

Reaction Steps

A mixture of 70 g (0.5 mole) dimethyl diallyl silane and 204.6 g (1.1 m mole, 10% excess over equivalent amounts) of diphenyl phosphine was reacted in the manner described in Example 1 at 40° C. The addition was slow. After 24 hours, only about 10% of the diphenyl phosphine reacted. The irradiation of the reaction mixture was continued for a total of 160 hours. A subsequent fractional distillation provided 46 g of monoadduct, as a clear, slightly viscous liquid monoadduct of bp. 122°-134° C. at 0.05 mm and 113 g of the desired diadduct (Table 1) as a clear, light yellow, viscous liquid.
