  AbstractThe reactions of diaryl-, aryl-, and alkyl–arylcyclopropanes with ethyl nitrite in the presence of sulfur trioxide and sulfur trioxide dioxane complex, as well as the reactions of 1-alkyl-2-arylcyclopropanes with NOBF4 were studied. It was found that the attack of the nitrosonium cation, accompanied by the formation of a benzyl carbocation, leads to the formation of isoxazolines. The introduction

  摘要在三氧化硫和三氧化硫二恶烷络合物存在下，二芳基，芳基和烷基芳基环丙烷与亚硝酸乙酯的反应，以及1-烷基-2-芳基环丙烷与NOBF 4的反应被研究了。已发现，亚硝基阳离子的侵蚀伴随着苄基碳阳离子的形成导致异恶唑啉的形成。将大量的烷基取代基引入环丙烷环中会改变亚硝化的区域选择性，有利于亲电粒子在苄基位置上的进攻，并导致形成烷基碳阳离子的竞争性形成。取决于烷基取代基的结构，形成了伴随骨架重排的分子内杂环化产物和在外部亲核试剂参与下形成的产物。

  The 9,10-dicyanoanthracene (DCA)-sensitized photoreaction of 1,2-diarylcyclopropanes 1a-d in nitrogen oxide (NO)-saturated CH3CN afforded 3,5-diaryl-2-isoxazolines 2a-d in excellent yields. The reaction of 1a-d with NOBF4 or with a mixture of NO and O2 in CH3CN also afforded 2a-d or 2a-b. These reactions proceed via the attack of NO on the radical cation of 1, which is formed by electron transfer from 1 to 1DCA* or NO+. The reaction of 1-alkyl-2-arylcyclopropanes with NOBF4 afforded mixtures of 3-alkyl-5-aryl-2-isoxazolines and 4-alkyl-5-aryl-2-isoxazolines via the direct attack of NO+ on the cyclopropane rings. The reaction of 1,1,2,2-tetraphenylcyclopropane with NOBF4 afforded 2,3,5,5-tetraphenyl-2-isoxazolinium tetrafluoroborate via the migration of the phenyl group to nitrogen.
