Put a ring on it! The arylation of aliphatic alcohols and hydroxide with diaryliodonium salts, to give alkyl aryl ethers and diaryl ethers, has been studied using experimental techniques and DFT calculations. Aryne formation and alcohol oxidation pathways were observed in parallel to arylation, and additives to avoid by-product formation originating from arynes have been found. A novel, direct nucleophilic
戴上戒指!已经使用实验技术和DFT计算研究了脂肪族醇和氢氧化物与二芳基碘鎓盐的芳基化,以得到烷基芳基醚和二芳基醚。观察到芳基形成和醇氧化途径与芳基化同时进行,并且发现了避免源自芳烃的副产物形成的添加剂。在与缺电子的二芳基碘鎓盐的反应中已经鉴定出新颖的直接亲核取代途径。
