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. 25245-27-6, name is 1-Iodo-3,5-dimethoxybenzene, A new synthetic method of this compound is introduced below., Recommanded Product: 1-Iodo-3,5-dimethoxybenzene
1. Condensation reaction: in with a thermometer, condenser 250 ml four bottle is added between the 26.7g 5 – iodo – teredimethyl ether, 12.8g bromopropylene, 20.4g triethylamine, 2.2g dppp nickel chloride, 130 ml methyl tert-butyl ether, magnetic stirring, oil bath heating, when the temperature rises to 80 C and maintaining at 4 hours, after the reaction is cooled to ambient temperature, for 60 ml 10% hydrochloric acid aqueous solution washing the reaction liquid, water washed to neutral, the organic layer is distilled under reduced pressure to obtain between the 21.4g 5 – propenyl – teredimethyl ether, yield 96.1%.
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.
