A mild and general cycloaddition of arynes with iodonium ylides protocol has been developed for the synthesis of benzofurans. In the presence of CsF, ortho-silyl aryltriflates were reacted with iodonium ylides smoothly at room temperature in moderate to good yields.
已经开发了具有碘鎓碘化物方案的温和且普通的芳烃环加成反应,用于合成苯并呋喃。在存在CsF的情况下,在室温下使正甲硅烷基芳基三氟甲磺酸酯与碘鎓碘化物平稳地反应,产率中等至良好。
