Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 2398-37-0, name is 1-Bromo-3-methoxybenzene, A new synthetic method of this compound is introduced below., Product Details of 2398-37-0
Intermediate 1 l-AUyl-3-methoxy-benzene (Ha)A solution of 3-bromoanisole (4Og, 0.2138mol) dissolved in dry THF (220 rnL) was added dropwise to a solution of magnesium (7.9g, 0.328mol) activated by pinch of iodine in dry THF (20 ml) and the reaction was shortly heated with a heat -gun to get the reaction started. After 1 hr, when the solution was gray and most of the magnesium was dissolved, allyl bromide (28.4 mL, 0.328 mol) was added. After 3 h the reaction was quenched by a saturated NH4Cl solution and the organic layer was extracted with diethyl ether. The organic phase was dried over anhydrous Na2SO4, the solvent was evaporated and the crude product was subjected to flash chromatography on silica gel (230-400 mesh) using 3-4% ethyl acetate in petroleum ether which gave the allyl compound as yellow viscous liquid (24 g, 76%).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
