Electric Literature of 96424-68-9, 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 96424-68-9, name is 2-Bromo-3-chloropyridine. This compound has unique chemical properties. The synthetic route is as follows.
To a flame-dried flask were added Pd(PPh3)4 (10 mol %), Xantphos (10 mol %), Cs2CO3 (3 eq) and 2-bromo-3-chloropyridine (1.2 eq). Then, 1OB (1 eq) and DMF (0.15 M) were added to the reaction mixture under an N2 atmosphere. The reaction mixture was stirred for 10 min at room temperature, and then heated at 140 C. in a pre-heated oil bath for 24 h. After that, the reaction mixture was cooled to room temperature, diluted with CH2Cl2, filtered through a short pad of Celite, and washed with CH2Cl2. The combined organic extracts were concentrated under reduced pressure and the resulting residue was purified by column chromatography on silica gel to provide the product DFE-1OB-3 in 36% yield.
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 96424-68-9, 2-Bromo-3-chloropyridine.
