A carboxylative Ni-catalyzed tandem C–C σ-bond activation of cyclobutanones followed by CO2-electrophilic trapping is documented as a direct route to synthetically valuable 3-indanone-1-acetic acids. The protocol shows an adequate functional group tolerance and useful chemical outcomes (yield up to 76%) when AlCl3 is adopted as an additive.

环丁酮的羧化 Ni 催化串联 C-C σ-键活化,然后是 CO 2 -亲电捕获被证明是合成有价值的 3-茚满酮-1-乙酸的直接途径。当采用 AlCl 3作为添加剂时,该协议显示出足够的官能团耐受性和有用的化学结果(产率高达 76%) 。目标循环支架的操作和基于实验证据的机械建议完成了调查。
