Application of 4,5-Dimethyl-1,3-dioxol-2-one

This molecular description is the mechanism of the reaction; it describes how individual atoms, ions, or molecules interact to form particular products. The stepwise changes are collectively called the reaction mechanism.

An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.4,5-Dimethyl-1,3-dioxol-2-one, cas is 37830-90-3. Here is a downstream synthesis route of the compound 37830-90-3, 37830-90-3

EXAMPLE 1 Preparation of 4-chloro-4-methyl-5-methylene-1,3-dioxolane-2-one (III) To a solution of 50 g of 4,5-dimethyl-1,3-dioxolene-2-one (IV)(Synthesised by the method described in Tetrahedron Letters, 1701-1704 (1972)) in 350 ml of methylene chloride was added 65 g of sulfuryl chloride dropwise over 1 hour at 40¡ã-42¡ã C. The mixture was stirred for one hour at the same temperature and then evaporated in vacuo to remove the solvent. The resulting residue was distilled in vacuo to obtain 42.1 g (65percent of theory) of 4-chloro-4-methyl-5-methylene-1,3-dioxolane-2-one (III) as a colorless oil. B.p. 45¡ã-48¡ã C./2 mmHg. IR(CHCl3)nu(cm-1): 1820, near 1695 etc. NMR(CDCl3, delta(ppm)): 2.19(3H, s, CH3), STR5
