invert　　

20. The energy of the trans conformation of the anion is 7.57 kJ/mol lower than the cis conformation, and the energy barrier of the conformation invert is only 3.05 kJ/mol. It shows the conformation invert reaction is controlled by thermodynamics and will happen easily. The result can explain the epimerization of 2-benzyl-2-ethoxycarbonyl-cyclopentanol in Williamson ether synthesis.
其中，醛基与酯羰基形成的反式构象的负离子能量比顺式构象的负离子能量低7.57 kJ/mol，而构象翻转的活化能仅为3.05 kJ/mol，说明构象翻转为热力学控制的反应，顺式构象即能够自发翻转呈反式构象，解释了在Williamson醚合成反应中顺、反构型翻转的现象。
