6940-78-9, Adding some certain compound to certain chemical reactions, such as: 6940-78-9, name is 1-Bromo-4-chlorobutane, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 6940-78-9.
Add p-nitrophenol (1.39g, 10mmol) and potassium carbonate (1.38g, 10mmol) to 25ml acetonitrile, then add dropwise1-Bromo-4-chlorobutane (1.7 ml, 15 mmol) was refluxed at 80 C overnight. After the reaction is completed, water is added to dissolve potassium carbonate, andExtract with ethyl acetate, wash the organic phase with saturated sodium bicarbonate and brine.Evaporation to dryness gave a white solid (1.98 g, yield 86%).The product was used directly in the next reaction without purification.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 6940-78-9.
