The cation radical Diels–Alder reactions of a series of meta and para substituted aryl cis-prop-1-enyl ethers with 2,3-dimethylbuta-1,3-diene catalyzed by tris(4-bromophenyl)aminium hexachloroantimonate have been studied mechanistically. The reactions are found to occur primarily via an indirect route involving cation radical cyclobutanation followed by cation radical vinylcyclobutane rearrangement
机械地研究了三(4-溴苯基)铵六氯锑酸盐催化的一系列间位和对位取代的芳基顺-丙-1-烯基醚与2,3-二甲基丁-1,3-二烯的阳离子基团狄尔斯-阿尔德反应。。发现反应主要通过涉及阳离子自由基环丁烷化然后阳离子自由基乙烯基环丁烷重排的间接途径发生。动力学研究表明,这些醚的电离作用是通过内球机理实现的。
