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. 32024-15-0, name is 3-Iodo-4,5-dimethoxybenzaldehyde, A new synthetic method of this compound is introduced below., Recommanded Product: 3-Iodo-4,5-dimethoxybenzaldehyde
General procedure: K2CO3 (2.5 × 10-4 mol, 2.5 equiv), aryl iodide (1.0 × 10-4 mol, 1.0 equiv), and alkyne (1.5 × 10-4 mol, 1.5 equiv) were mixed in a 10-mL vial, followed by addition of a solution of the selected catalyst (1 × 10-8 mol) in EtOH (1 mL). The vial was placed in a preheated oil bath at 80 C and stirred for 1 h. After cooling to 20-25 C, the reaction mixture was evaporated to dryness under a stream of dinitrogen followed by addition of 1.0 equiv of 1,2-dimethoxyethane as NMR internal standard, and extraction of the reaction mixture with three 0.20-mL portions of CDCl3. All fractions were joined and analyzed by 1H NMR spectroscopy. The product peak assignments were based on the authentic samples or on published dat, whereas quantifications were performed upon integration of the selected peak of the product relatively to the peak of the standard.
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.
