Effect of areneâarene interaction in stereoselective MCPBA epoxidation was investigated using 5,6-dimethyl-2-phenyl-3a,4,7,7a-tetrahydroisoindole-1,3-diones 1. From the good correlation between the stereoselectivity of the products and Hammettâs coefficients of para-substituents (ÏP) on the phenyl group, it was found that polar/Ï interaction between the phenyl group and MCPBA is the main interaction for controlling the stereoselectivity in the reaction. Other areneâarene interactions, charge-transfer complexation and edge-to-face interaction, were assumed to be much weaker than polar/Ï interaction in this reaction.
研究人员使用 5,6-二甲基-2-苯基-3a,4,7,7a-四氢异吲哚-1,3-二酮 1 研究了在立体选择性 MCPBA 环氧化反应中芴和蒈烯相互作用的影响。从产物的立体选择性与苯基上对位取代基(ÏP)的哈米特系数之间的良好相关性可以发现,苯基与 MCPBA 之间的极性/Ï 相互作用是控制反应立体选择性的主要相互作用。在该反应中,其他的炔蒈烯相互作用、电荷转移复合作用和边-面相互作用被认为比极性/Ï相互作用弱得多。
