Versuchsvorschrift

300 mmol of Methylacrylic acid (MAA) and 200 mmol of chloromethyl trimethylsilane were dissolved in 400 ml of dimethylamide. Potassium carbonate was added to the solution and heated to 90° C. and stirred for 5 hours. Next, the reaction solution was filtered. The filtrate was added to a sodium hydrogen carbonate solution, extracted with ether and pure water respectively, dried, filtered, and concentrated to obtain trimethylsilanylmethyl methylacrylate (TMSA) having the formula (i) below
