The radical cat ions of styrene (π-type), generated by photosensitized electron-transfer of 1,4-dicyanobenzene (DCB), using 2-methyl-2-nitrosopropane (MNP) as spin trap ping agents and nucleophiles as the co-reactant were investigated. The spin-trapped nitroxide radicals were subjected to HPLC-ESR and mass spectroscopic studies. Long-range hfsc were obtained by resolution enhancement. Mass spectral
苯乙烯的自由基阳离子(π 型),由 1,4-二氰基苯 (DCB) 的光敏电子转移产生,使用 2-甲基-2-亚硝基丙烷 (MNP) 作为自旋捕获剂和亲核试剂作为共-反应物进行了研究。对自旋捕获的氮氧自由基进行 HPLC-ESR 和质谱研究。通过分辨率增强获得远程 hfsc。质谱碎片模式支持捕获的氮氧化物的区域选择性形成,这是由甲醇在苯乙烯阳离子自由基的 β 位上的反马尔科夫尼科夫加成得到的。
