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。
The main reaction sites of tritium gas with unsaturated organic compounds - irisquinone and isoprothiolane fumarate are not electrophilic addition reaction of carbon-carbon double bond but electrophilic substitution reaction in other positions. The calculation of CNDO / 2 shows that the π-electron polarizability (the degree of dissociation) at the reaction site is larger than the carbon-carbon double bond.
