ether, the arylating agent and the catalytic system. In this study, an effective and practical method was successfully developed for the synthesis of acetophenones with high regioselectivity under palladium-catalyzed conditions. A variety of acetophenones was readily prepared from aryl iodides in good to excellent yields under microwave irradiation in a single step. The key feature of our new protocol
烯醇醚的
钯介导的芳基化(Heck芳基化)的区域
化学对烯醇醚,芳基化剂和催化体系的结构敏感。在这项研究中,成功地开发了一种有效且实用的方法,用于在
钯催化的条件下合成具有高区域选择性的
苯乙酮。在微波辐射下,一步就可以从芳基
碘化物容易地制得各种
苯乙酮,收率好至极好。我们新协议的关键特征是使用
乙烯基氧基三甲基
硅烷作为高度区域选择性酰化试剂。
