実験手順
The following were charged to a 1 L roundbottom flask equipped with a stirrer and thermometer: 200 g 1.3-di(2-methylphenethyl)tetramethyldisiloxane as prepared in Example 3, 600 g 1,3-divinyltetramethyldisiloxane, and 5 g thoroughly dehydrated activated clay. This was followed by heating to 80° to 85° C. and stirring for 2 hours. The reaction mixture was then filtered and the filtrate was heated in vacuo to afford 160 g 1-(2-methylphenethyl)-3-vinyltetramethyldisiloxane.
