Web11 okt. 2024 · Application of sonochemistry for the synthesis of different coumarin derivatives is also useful due to better yield and shorter reaction time compared with the classical procedures (entry 10). 6,8-Diiodocoumarin derivatives have also been synthesized in good yields by Knoevenagel condensation using piperidine as catalyst (entry 11). WebPotassium iodide (KI) is a chemical compound that can be used as an iodide ion source for nucleophilic displacement reactions. During the electrochemical oxidation of aldehydes, it acts as a mediator. In the presence of an acid, it can cleave some ethers. KI can iodinate aromatic and organothallium compounds in the presence of an oxidizing agent.
Web2-iodophenols dissolved in acetone (4 equiv) was added with α-bromoaceto- phenones (1.1 equiv) and anhydrous K2CO3 (1.5 equiv). The resulting mixture was stirred for 2 h at room temperature. After filtration, the solvent was evaporated under reduced pressure. The residue was purified by the recrystallization method using alcohol. 4.
