Rhodium(III)-catalyzed C–H activation of (hetero)arenes and redox-neutral coupling with 2-carboxyl allylic alcohols has been realized for the construction of β-aryl ketones. This reaction occurred efficiently at a relatively low catalyst loading via initial dehydrogenative alkylation to give a β-keto carboxylic acid, followed by decarboxylation.

Rh（III）催化（杂）芳烃与2-羧基烯丙醇的无受体脱氢偶联

铑（III）催化（杂）芳烃的CH活化和2-羧基烯丙基醇的氧化还原中性偶联已被用于构建β-芳基酮。该反应通过初始的脱氢烷基化反应以较低的催化剂负载量有效地发生，得到β-酮基羧酸，然后进行脱羧反应。
