【摘要】 氚气与不饱和有机化合物——马蔺子甲素和异普罗匹拉富马酸盐的主要反应位置不是碳-碳双键的亲电加成反应,而是在其它位置发生亲电取代反应。CNDO/2计算指出,反应位置的π电子可极化率(超离位度)比碳-碳双键大。更多还原

【Abstract】 The sites of principal reactions o fthe unsaturated organic compounds——irisquinone andisopropiramfumarate with tritium gas were determined, The results showed that the reaction was principally not electrophilic addition on the carbon-carbon double bond, but the tritium incorporated by electrophilic substitution was attached to the carbon bonds. CNDO/ 2 calculations showed that the π-electron polarizability (superdelocalizability) of the reaction sites was greater than that of the carbon-carbon double bond.更多还原
