A simple and efficient method for the coupling of aryl iodides with aliphatic alcohols and phenols that does not require the use of alkoxide bases is described. This C-O bond forming procedure shows that the combination of air stable CuI and 1,10-phenanthroline in the presence of KF/Al2O3 comprises an extremely efficient and general catalyst system for the etherification of aryl iodides. Different functionalized aryl iodides were coupled with alcohols and phenols using this method.
本文介绍了一种无需使用氧化烷基即可实现芳基碘化物与脂肪醇和苯酚偶联的简单而高效的方法。这一 C-O 键形成过程表明,在 KF/Al2O3 存在下,空气稳定的 CuI 和 1,10-菲罗啉的组合是芳基碘化物醚化过程中极为高效的通用催化剂体系。用这种方法将不同官能化的芳基碘化物与醇类和酚类偶联。
