The reaction between an acceptor olefin (symbolized as CC and substituted by at least one conjugatively electron-withdrawing group) and N-tert-butylhydroxylamine in the presence of t-BuNO as an oxidant gives an aminoxyl which formally is a spin adduct of HC–C˙ and t-BuNO and in the appropriate cases identical to the aminoxyl formed in the thermal or photochemical reaction between CC and α-phenyl-N-tert-butylnitrone
受体烯烃(符号化为C之间的反应C和由至少一个conjugatively吸电子基团取代)和ñ -叔在存在-butylhydroxylamine吨-BuNO作为氧化剂使氨基氧形式上是HC的自旋加合物-C和吨-BuNO并在相同的形成在C之间的热或光化学反应的氨基氧的适当情况下C和α苯基ñ -叔-butylnitrone(PBN)。研究的受体烯烃为N-苯基马来酰亚胺,马来酰亚胺,N-甲基马来酰亚胺,马来酸酐,富马酸二乙酯,2,3-(2 H 2)富马酸酯,马来酸二乙酯,三羧酸三甲酯,1,4-苯醌,富马腈,丙烯酸甲酯,甲基丙烯酸甲酯和丙烯腈。
