Abstract For the first time the reactions of radical nitration of alkenes and oxiranes with nitrogen dioxide in the liquid and supercritical carbon dioxide (sc-CO2) media were carried out. Using octene-1, styrene, and their derivatives as examples, the effectiveness of the developed method for obtaining valuable 1,2-functionalized products, including nitroalcohols, dinitroalkanes, and nitronitrates
摘要 首次在液体和超临界二氧化碳 (sc-CO 2 ) 介质中进行烯烃和环氧乙烷与二氧化氮的自由基硝化反应。以 octene-1、苯乙烯及其衍生物为例,该方法在获得有价值的 1,2-官能化产品(包括硝基醇、二硝基烷烃和硝酸盐)方面的有效性已得到证实。由于sc-CO 2的应用,所提出的方法与已知的类似物相比具有优势,因为没有副产物和废有机溶剂,以及较小的火灾和爆炸危险。
