We have developed a new strategy that uses the Krohnke synthesis for the preparation of various substituted phenylpyridines in excellent yields (up to 88 %). Starting with the appropriate commercially available acetophenone, a variety of phenylpyridines substituted by either electron-donating (i.e. methyl, methoxy) or -withdrawing groups (i.e. bromide, nitro) on the phenyl ring are obtained in a two-step
我们开发了一种新策略,该策略使用 Krohnke 合成以优异的产率(高达 88%)制备各种取代的苯基吡啶。从合适的市售苯乙酮开始,在两步合成中获得在苯环上被供电子(即甲基、甲氧基)或吸电子基团(即溴、硝基)取代的多种苯基吡啶。相应的官能化环金属化钌配合物可以通过以下方式以异常高的产率制备
