The effects of the ratio of reactants , condensation reaction time, condensation reaction temperature on the product yield had been investigated. The optimum synthesis conditions were determined that the condensation reaction took place at 45℃- 50℃ for three hours with the male ration of bromobenzene and magnesium powder = 1 : 1. 1, of bromobenzene and dichlorodiphenylsilane = 1:0.8, the yield of triphenylsilanol was above 74.57% , and mass fraction of triphenylsilanol in the product was above 98%. The structure of product was confirmed by IR.
