The radical intermediates involved in the photolysis of alicyclic nitrites have been identified by EPR spectroscopy. In particular, cyclobutyl nitrite allows detection of the 2-pyrrolidinone-1-oxyl whose formation involves a 1,5-exo ring closure process which the 4-nitroso-1-acyl radical intermediate can undergo. Furthermore, experimental evidence supports for the formation of the alkyl alkoxy nitroxides
通过EPR光谱已鉴定出涉及脂环式亚硝酸盐光解的自由基中间体。特别地,环丁基亚硝酸盐允许2-吡咯烷酮-1-氧基,其形成包括1,5-检测外切环闭合过程其中4-亚硝基-1-酰基中间体可经历。此外,实验证据支持形成烷基烷氧基氮氧化物的不同反应机理,该机理涉及烷基和未反应的亚硝酸盐。
