Versuchsvorschrift

To a 25 mL three-necked reaction flask, 3.55 mL (0.03 mole) of α-toluenethiol, 0.58 g (1.5×10-3 mole) of benzyl triphenyl phosphonium chloride and 15 mL (0.03 mole) of 2N NaOH solution were added. The resulting solution was heated to 82° C. with agitation for one hour. Thereafter, 2.3 mL (0.027 mole) of methacrylic acid was added dropwise over a 30 minute period to the preheated mixture, and the reaction mixture was heated to 125° C. and maintained under reflux for 18 hours.
