potential of nonstabilized diazo compounds, their utilization has always been hampered by stability, toxicity, and safety issues. The present method opens up access to the most reactive nonstabilized diazoalkanes. Among diazo compounds, nonstabilized alkyl diazo compounds are the least represented because of their propensity to degrade during preparation. The continuous flow oxidation process of hydrazones
尽管不稳定的重氮化合物具有很高的合成潜力,但其使用一直受到稳定性,毒性和安全性问题的阻碍。本方法打开了反应性最强的不稳定的重氮烷烃的途径。在重氮化合物中,不稳定的烷基重氮化合物代表最少,因为它们在制备过程中易于降解。oxide在氧化银柱上的连续流动氧化过程提供了不含碱和金属的纯重氮二氯甲烷溶液的输出物流。从无毒的酮和醛开始,这种方法可以以优异的收率生产各种前所未有的重氮烷烃化合物,同时突出了其合成潜力和安全大规模重氮生产的可能性。
