Nitro compounds serve as valuable intermediates for pharmaceuticals, agrochemicals, dyes, and polymers. In recent years, radical nitration using tert-butyl nitrite (t-BuONO) has attracted wide attention and desirable progress has been made. On the one hand, t-BuONO is a potential active nitro radical source and can react with various functional groups. On the other hand, as a green and novel nitration reagent, t-BuONO has relatively low price and can easily produce a radical under mild conditions, which undoubtedly provides a simple and efficient way for nitration reactions. To date, some important reviews are available that summarize the synthesis of nitro compounds. To the best of our knowledge, however, there is still no review that exclusively discusses the synthesis of nitro compounds using t-BuONO through a radical strategy. Therefore, this review aims to highlight the recent advances in radical nitration using t-BuONO as nitration reagent. The main progress in this area has been presented according to the type of reaction substrates. Special attention has been paid discussion of the reaction mechanisms and selected examples of substrates have been given. We hope this paper will be a useful reference and inspiration for those who are exploring the synthesis of nitro compounds using t-BuONO.

叔丁基亚硝酸盐自由基硝化的最新进展

硝基化合物可作为医药，农药，染料和聚合物的重要中间体。近年来，使用亚硝酸叔丁酯（t- BuONO）的自由基硝化引起了广泛关注，并且已经取得了令人满意的进展。一方面，t -BuONO是潜在的活性硝基自由基源，可以与各种官能团反应。另一方面，作为一种绿色新颖的硝化试剂，t-BuONO价格相对较低，在温和条件下可以轻松产生自由基，这无疑为硝化反应提供了一种简单有效的方法。迄今为止，已有一些重要的综述总结了硝基化合物的合成。然而，据我们所知，目前尚无任何评论专门讨论通过自由基策略使用t- BuONO合成硝基化合物。因此，本综述旨在强调使用t进行自由基硝化的最新进展。-BuONO作为硝化试剂。已经根据反应底物的类型介绍了该领域的主要进展。已经特别注意了反应机理的讨论，并给出了底物的选定实例。我们希望本文对那些使用t- BuONO合成硝基化合物的研究者提供有用的参考和启发。
