A Tert‐butyl Peroxybenzoate (TBPB) mediated cycloalkylation and formamidation efficiently took place at 120°C in chlorobenzene or the corresponding formamide, respectively. The cycloalkylation required the addition of acetic acid, whereas the formamidation proceeded in its absence. This radical‐mediated process tolerated a broad scope of substrates and provided the products in moderate to good yields.

TBPB 介导的 4-芳基香豆素的 C-3 环烷基化和甲酰胺化

过氧苯甲酸叔丁酯 (TBPB) 介导的环烷基化和甲酰胺化分别在 120°C 下在氯苯或相应的甲酰胺中有效发生。环烷基化需要加入乙酸，而甲酰胺化则在没有乙酸的情况下进行。这种自由基介导的过程可以耐受广泛的底物，并以中等至良好的产率提供产品。
