We know that the rate of many reactions can be accelerated by catalysts. A catalyst speeds up the rate of a reaction by lowering the activation energy; in addition, the catalyst is regenerated in the process. 37830-90-3, molecula formula is C5H6O3, below Introduce a new synthetic route., 37830-90-3
PREPARATION 1 4-Bromomethyl-5-methyl-2-oxo-1,3-dioxole To a stirred solution of 3.0 g of 4,5-dimethyl-2-oxo-1,3-dioxole in 100 ml of carbon tetrachloride was added 4.63 g of N-bromosuccinimide. The resulting solution was heated under reflux and irradiated for 15 minutes. The reaction mixture was cooled to 0¡ã-5¡ã C., filtered and evaporated to give the title product. The NMR spectrum (CDCl3) showed absorptions at 2.05 (5percent of starting material), 2.18 (3H, s), 4.30 (2H, s) and 4.35 (5percent of dibromo compound) ppm downfield from tetramethylsilane. The infrared spectrum showed an absorption at 5.49 microns., 37830-90-3
Elementary reactions that involve the simultaneous collision of more than three molecules are highly improbable and have never been observed experimentally.
