Name is Isothiazole, as a common heterocyclic compound, it belongs to isothiazole compound, and cas is 288-16-4, its synthesis route is as follows.,288-16-4
Compound 1 (20 g, 0.235 mol) was added under stirring with nitrogen to dry 100 ml of ether and stirred to dissolve,And then cooled to below 0 ,To this was added n-butyllithium (0.24 mol)During the dropping process, the temperature was kept below 0 C,After the dropwise addition, the incubation reaction was carried out until no compound 1 was added.To the reaction solution was added bromine (0.5 mol)During the dropping process, the temperature was kept below 0 C,After the dropwise addition, slowly raise to room temperature,After stirring for half an hour, the reaction was quenched by the addition of hydrochloric acid solution (2N, 500 ml).The aqueous phase was extracted with ether (200 ml * 3) and discarded.The combined organic phase, sodium dithionite solution (100 ml * 2)Dried over anhydrous sodium sulfate, filtered and concentrated to dryness,A yellow oily compound was prepared.
With the complex challenges of chemical substances, we look forward to future research findings about Isothiazole
