The anti-Markovnikov hydronitration and hydronitroalkylation of alkenes by using cooperative photoredox catalysis and hydrogen atom abstraction has been developed to access an important class of molecules—nitroalkanes. The image shows a vibrant beam of visible light directed into a flask containing bench-stable, redox-active organic nitrating reagents, either N-nitrosuccinimide or gem-bromonitroalkanes, generating a controlled number of bubbles that transport reactive nitryl or nitroalkyl radicals. The unique molecules surrounding the flask and carried by bubbles symbolize the novelty of the reported method, drawing attention and inviting scientists to explore the world of radical nitration chemistry in greater depth.

通过使用协同光氧化还原催化和氢原子提取对烯烃进行反马尔科夫尼科夫氢硝化和氢硝基烷基化已经开发出来，以获得一类重要的分子——硝基烷烃。该图像显示了一束充满活力的可见光，射入装有工作台稳定、氧化还原活性有机硝化试剂（N-亚硝基琥珀酰亚胺或宝石-溴硝基烷烃）的烧瓶中，产生可控数量的气泡，这些气泡可运输反应性硝酰基或硝基烷基自由基。烧瓶周围和气泡携带的独特分子象征着所报道方法的新颖性，引起了人们的注意并邀请科学家更深入地探索自由基硝化化学的世界。更多信息可以在 S. Patra 和 D. Katayev 的研究文章 （DOI： 10.1002/chem.202403654） 中找到。
