37830-90-3, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.37830-90-3. An updated downstream synthesis route of 37830-90-3 as follows.
37830-90-3, To a solution of 4,5-dimethyl-1,3-dioxolene-2-one (TCI, 10 g, 88 mmol) and N- bromosuccinimide (Fluka, 15.69 g, 88 mmol) in carbon tetrachloride (250 mL) was added benzoyl peroxide (Acros, 500 mg, 2.1 mmol). The reaction mixture was then refluxed for 2.5 h after which time the volatiles were evaporated under vacuum. The resulting residue was triturated with some carbon tetrachloride, filtered and the solid cake was washed with carbon tetrachloride. The filtrate volatiles were removed under vacuum and the yellow oily residue was distilled under vacuum (2-5 torr) to give 4-bromomethyl-5-methyl-1,3-dioxolene-2-one 903 (8.35 g, b.p. 94-98 ¡ãC, 49percent) as a pale yellow oil. 1H NMR (CDCI3) 8 4.21 (s, 2H), 2.17 (s, 3H).
A chemical reaction often occurs in steps, although it may not always be obvious to an observer.
