Abstract: Vinyl-functional alcohols are silylated by reaction with a hydrolysable silyl hydride compound. The starting alcohol is heated and then combined with the silyl hydride and catalyst and allowed to heat exothermically. Cooling is applied when the conversion of vinyl groups is between 90-99%. In some embodiments, specified amounts of water are present. The cooling regimen and control of water content reduces certain side reactions, leading to greater yields to desired product.
