Adding a certain compound to certain chemical reactions, such as: 702-98-7, 2-Methyladamantan-2-ol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Formula: C11H18O, blongs to alcohols-buliding-blocks compound. Formula: C11H18O

A reactor made of glass was charged with 110 g of toluene, 50 g of n-undecane, 80 g of 2-methyladamantanol, 4.1 g of methacrylic acid and 0.92 g of p-toluenesulfonic monohydrate. The resulting mixture was heated until the reflux of toluene occurred, followed by reflux for 2 hours while distilling off water, whereby 2-methyleneadamantane was prepared it was then cooled to 0 C. A methacrylate forming reaction was carried out by adding 103.6 g of methacrylic acid and 13.7 g of boron trifluoride ethyl ether to it and stirring the resulting mixture for 2 hours. The reaction mixture was washed with 1275.5 g of a 10% aqueous sodium carbonate solution, followed by washing three times with 160 g of deionized water. Toluene was then distilled off at 70 C. under reduced pressure, whereby 148.8 g of crude 2-methyladamantan-2-yl methacrylate was obtained.
