Continuously updated synthesis method about 37830-90-3

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.37830-90-3, you can also check out more blogs about37830-90-3

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 37830-90-3. In a patent£¬Which mentioned a new discovery about 37830-90-3, molcular formula is C5H6O3, introducing its new discovery.

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
