are quite different. The two forms can be obtained by different transition metal-catalyzed reactions. To assign meso and racemic structures, a novel method is reported in which experimental gas-phase ion mobility data are compared with theoretical structures obtained from molecular mechanics calculations.
反式-1,2-双([2.2] 对环芳基)
乙烯 (1) 以一对非对映异构体的形式存在,其构象和有效碰撞截面完全不同。这两种形式可以通过不同的过渡
金属催化反应获得。为了分配内消旋和外消旋结构,报告了一种新方法,其中将实验气相离子迁移率数据与从分子力学计算获得的理论结构进行比较。
