Electric Literature of 796851-03-1, 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 796851-03-1, name is 2,5-Dichloro-4-iodopyridine. This compound has unique chemical properties. The synthetic route is as follows.
A mixture of 2,5-dichloro-4-iodopyridine (3.86 g, 14.09 mmol, 1.00 equiv), 5-(tetramethyl- 1,3,2-dioxaborolan-2-yl)-2-(trifluoromethyl)pyrimidine (4.26 g, 15.54 mmol, 1.10 equiv), potassium carbonate (5.83 g, 42.19 mmol, 2.99 equiv), and Pd(dppf)C12 (516 mg, 0.70 mmol, 0.05 equiv) in dioxane (50 mL)/water (5 mL) was stirred for 12 h at 60C under nitrogen. The solids were filtered out. The filtrate was diluted with ethyl acetate, washed with brine, dried over anhydrous sodium sulfate, and concentrated under vacuum. The residue was purified by a silica gel column eluting with acetate/petroleum ether (1/100) to afford the title compound (2.2 g, 53%) as a yellow solid.
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 796851-03-1, 2,5-Dichloro-4-iodopyridine.
