common and versatile reagent. Its synthesis from olefin is generally limited by the formation of mixture of cis and trans compounds. Here we report that silver nitrite (AgNO2) along with TEMPO can promote the regio- and stereoselective nitration of a broad range of olefins. This work discloses a new and efficient approach wherein starting from olefin, nitroalkane radical formation and subsequent transformations
硝基烯烃是一种常见且用途广泛的试剂。它从烯烃合成通常受到顺式和反式化合物混合物的形成的限制。在这里,我们报告亚硝酸银 (AgNO2) 与 TEMPO 一起可以促进范围广泛的烯烃的区域和立体选择性硝化。这项工作公开了一种新的有效方法,其中从烯烃开始,硝基烷烃自由基形成和随后的转化以立体选择性方式导致所需的硝基烯烃。
