The origin of a common compound about 37830-90-3

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 4,5-Dimethyl-1,3-dioxol-2-one.C5H6O3

37830-90-3,is a common compound. C5H6O3.In an article, once mentioned the new application about 37830-90-3.

To a stirred solution of 4, 5-dimethyl-l, 3-dioxol-2-one (4.5 g, 39.4 mmol) in benzene (150 mL), were added NBS (15.44 g, 87 mmol) and AIBN (0.648 g, 3.94 mmol). The reaction mixture was stirred at 1 10 C for 2 h under nitrogen atmosphere and subsequently concentrated in vacuo. The residue was dissolved in ethyl acetate (200 mL). The solution was washed with water (2* 150 mL) and brine (100 mL), dried over anhydrous sodium sulphate and concentrated in vacuo to get the crude product as a light brownish oil, which was purified by CombiFlash chromatography (60-120 silica gel; 5- 55% ethyl acetate in pet. ether as eluent) to afford 4,5 -bis (bromomethyl)-l,3-dioxol-2- one (7 g, 66%) as a light yellowish oil. NMR (400 MHz, Chloroform-7) d ppm 4.22 (s, 4H).
