Herein, we report a conceptually novel borylation reaction proceeding via a mild photoinduced decarboxylation of redox-activated aromatic carboxylic acids. This work constitutes the first application of cheap and easily prepared N-hydroxyphthalimide esters as aryl radical precursors and does not require the use of expensive transition metals or ligands. The reaction is operationally simple, scalable, and displays broad scope and functional group tolerance.

N-羟基邻苯二甲酰亚胺酯的无过渡金属，可见光使能脱羧硼化

在本文中，我们报告了一种通过氧化还原活化的芳香族羧酸的轻度光诱导脱羧而进行的概念上新颖的硼酸酯化反应。这项工作构成了廉价和容易制备的N-羟基邻苯二甲酰亚胺酯作为芳基自由基前体的首次应用，并且不需要使用昂贵的过渡金属或配体。该反应操作简单，可扩展，并显示出广泛的范围和功能基团的耐受性。
