A method for the synthesis of etherified 3-(1H-1,2,3-triazol-1-yl)phenyl iodides from 1,4-disubstituted 1,2,3-triazoles under metal-free conditions has been developed. In the presence of ArI(OAc)2, a range of 1,2,3-triazole substrates that contain a hydroxy group underwent a direct O–H arylation and C–H iodination to give functionalized 1,2,3-triazoles in good to excellent yields.
已经开发了在无金属条件下由1,4-二取代的1,2,3-三唑合成醚化的3-(1 H -1,2,3-三唑-1-基)苯基碘化物的方法。在存在ArI(OAc)2的情况下,对一系列包含羟基的1,2,3-三唑底物进行直接的O–H芳基化和C–H碘化处理,可得到功能化的1,2,3-三唑达到优异的产量。
