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
REFERENCE EXAMPLE 2 Preparation of 4-chloromethyl-5-methyl-1,3-dioxolene-2-one (II) To a solution of 75 g of 4,5-dimethyl-1,3-dioxolene-2-one (IV) in 750 ml of methylene chloride was added 97.6 g of sulfuryl chloride dropwise at 40¡ã-42¡ã C. over 2 hours. The mixture was stirred for 40 minutes at the same temperature and evaporated in vacuo to remove the solvent. NMR spectrometry of the resulting oil revealed that the product was 4-chloro-4-methyl-5-methylene-1,3-dioxolane-2-one (III) containing a trace amount of unreacted 4,5-dimethyl-1,3-dioxolene-2-one (IV). This oil was heated at 90¡ã C. with stirring for 2 hours without isolating 4-chloro-4-methyl-5-methylene-1,3-dioxolane-2-one (III) and then distilled in vacuo. 75.4 g (corresponding to an overall yield from 4,5-dimethyl-1,3-dioxolene-2-one (IV) of 77percent) of 4-chloromethyl-5-methyl-1,3-dioxolene-2-one (II) having the physicochemical properties described in Reference Example 1 was obtained.
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps.
