The ruthenium-catalyzed reaction of aromatic ketones with arylboronic acid esters (arylboronates) gave the ortho arylation product. For this coupling reaction, a RuH2(CO)(PPh3)3 complex exhibited the highest catalytic activity among the complexes screened. Several aromatic ketones, for example, acetophenones, acetonaphthone, alpha-tetralone, and benzosuberone, can be used in this coupling reaction
芳族酮与芳基硼酸酯(芳基硼酸酯)在钌催化下反应得到邻位芳基化产物。对于这种偶联反应,RuH2(CO)(PPh3)3 配合物在筛选的配合物中表现出最高的催化活性。几种芳香酮,例如苯乙酮、乙酰萘、α-四氢萘酮和苯并芴酮,可用于该偶联反应。发现各种含有给电子(OMe 和 NMe2)和吸电子(F 和 CF3)基团的芳基硼酸酯与芳香酮反应生成相应的酰化产物。相应的芳基硼酸可用于该偶联反应,但与使用相应芳基硼酸酯的反应相比,产率略低。
