    Abstract: A method of preparing nitrocycloalkanones by simultaneously contacting a solution containing a cycloalkene, a denitrating agent and an organic solvent with a mixture of dinitrogen tetroxide and oxygen, the mole ratio of denitrating agent to cycloalkene being above 0.1:1 and up to about 2:1, preferably about 0.5:1 to 1:1, as a one step nitrooxidation reaction. The nitrocycloalkanones so formed are useful as fuel and lubricant additives as well as intermediates in the preparation of cyclic lactams such as caprolactam.

    Abstract translation: 通过将含有环烯烃,脱硝剂和有机溶剂的溶液与四氧化二氮和氧气的混合物同时接触来制备硝基环烷酮的方法,脱水剂与环烯烃的摩尔比大于0.1:1且高达约2:1 ,优选约0.5:1至1:1作为一步硝基氧化反应。 如此形成的硝基环烷酮可用作燃料和润滑剂添加剂以及制备环状内酰胺如己内酰胺的中间体。

    Abstract: A method of preparing nitrocycloalkanones by simultaneously contacting a solution containing a cycloalkene, a 2-pyrrolidinone denitrating agent and an organic solvent with a mixture of dinitrogen tetroxide and oxygen, the mole ratio of denitrating agent to cycloalkene being above 0.1:1 and up to about 2:1, preferably about 0.5:1 to 1:1, as a one step nitrooxidation reaction. The nitrocycloalkanones so formed are useful as fuel and lubricant additives as well as intermediates in the preparation of cyclic lactams such as caprolactam.
