Reaction Steps

A 250 ml round bottom flask, equipped with a reflux condenser and an oil bath with a magnetic stirrer was charged with 10.0 g (82 mmol) trimethoxysilane and 5.0 g (16.4 mmol) of 2-[[4-(prop-2-enyloxy)benzylidene]-malonic acid diethyl ester in 100 ml of toluene under nitrogen atmosphere. The reaction mixture was heated to 70° C. and a catalytic amount of divinyl-tetramethyl disiloxane platinum complex was added. After the reaction mixture was heated for 2 hours, the solution was concentrates and filtrated over Celite to yield 6.2 g (88%) of crude 2-[[4-[3-(trimethoxysilyl)propoxy]benzylidene]-malonic acid diethyl ester as yellow oil. UV (ethanol) 312 nm (24′793).
