The RuH2(CO)(PPh3)3-catalyzed C–H functionalization of aromatic esters with 5,5-dimethyl-2-aryl-[1,3,2]dioxaborinanes (arylboronates) gave the orthoarylation products. This coupling reaction can be performed with various combinations of isopropyl benzoate derivatives and arylboronates. Introduction of CF3 group in the aromatic ring increased the reactivity of the esters. Pinacolone effectively served
RuH 2(CO)(PPh 3)3催化的芳香族酯与5,5-二甲基-2-芳基-[1,3,2]二氧杂硼烷酮(芳基硼酸酯)的C–H官能化反应得到邻芳基化产物。该偶联反应可以用异丙基苯甲酸酯衍生物和芳基硼酸酯的各种组合进行。在芳环中引入CF 3基团增加了酯的反应性。Pinacolone有效地充当了由C–H键断裂产生的氢化物的接受体,并且使用的pinacolone的量也影响了芳基化产物的收率。
