PROBLEM TO BE SOLVED : To provide a production method by which a divinyl siloxane compound such as a divinyltrisiloxane is obtained in a high yield without using dimethyl vinyl chlorosilane.SOLUTION : A method of producing a divinyl siloxane compound represented by general formula (3) includes reacting of a silane diol compound with a divinyl siloxane compound by using an alkali metal catalyst. In the general formula(3), Ris an aryl group having 6 to 10 carbon atoms, Ris an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, a cycloalkyl group or a cycloalkenyl group having 5 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, or an aralkyl group having 7 to 10 carbon atoms, and Rand Rare each independently an alkyl group having 1 to 4 carbon atoms. |
