An efficient method was developed for the one-pot construction of C–B and C–I via visible light-induced transformation of nitroarenes. This protocol relies on the photochemical properties of nitroarenes under visible light, followed by reduction with B₂pin₂ and diazotization with ^tBuONO. An array of arylboronates and iodobenzenes were constructed smoothly after excitation with purple LEDs at room temperature. In addition, the synthetic utility of this method was further demonstrated in the late-stage modification of a drug molecule. The advantages of this strategy include metal-free system, mild reaction conditions and acceptable substrate scope.

可见光诱导的无金属级联硝基芳烃脱氮硼化和碘化

开发了一种通过可见光诱导硝基芳烃转化一锅法构建 C-B 和 C-I 的有效方法。该方案依赖于硝基芳烃在可见光下的光化学性质，然后用​​ B ₂ pin ₂还原并用^t BuONO 重氮化。在室温下用紫色 LED 激发后，顺利构建了芳基硼酸酯和碘苯阵列。此外，该方法的合成效用在药物分子的后期修饰中得到进一步证明。该策略的优点包括无金属体系、反应条件温和以及可接受的底物范围。
