Reference of 109-04-6, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 109-04-6, name is 2-Bromopyridine. This compound has unique chemical properties. The synthetic route is as follows.
General procedure: To a flame-dried Schlenk tube equipped with a magnetic stir bar was loaded alkyl bromide (0.15 mmol, 100 mol%, solid), halogenated pyridine (0.30 mmol, 300 mol%, solid), ligand (0.015 mmol, 10 mol%), zinc powder (0.45 mmol, 300 mol%). The tube was capped with a rubber septum and moved to a dry glove box, at which NiBr2 (0.015 mmol, 10 mol%), MgCl2 (0.15 mmol, 100 mol%) and Bu4NBr (0.075 mmol, 50 mol%) were added. Then the tube was moved out of the glove box. Alkyl bromide (0.15 mmol, 100 mol%, liquid), halogenated pyridine (0.30 mmol, 300 mol%, liquid), pyridine (0.15 mmol, 100 mol%) and DMA(1.0 mL) were added via syringe. After the reaction mixture was allowed to stir overnight under N2 atmosphere at 30 C, it was directly loaded onto a silica column without work-up. The residue in the reaction vessel was rinsed with small amount of DCM or eluent. Flash column chromatography provided the product as solid or oil.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 109-04-6, 2-Bromopyridine.
