stereocenters of rotaxanes up to 8.4 times and unexpectedly large steric kineticisotope effect on the deslipping reaction (ca. 20%) were observed. On the basis of the kinetic parameters, steric kineticisotope effect, and 1H NMR spectra of the nondeuteriated and deuteriated rotaxanes, we propose a deslipping mechanism involving pre-equilibrium.
观察到轮滑的非对映体立体中心差异高达8.4倍,并且对脱脂反应的空间动力学同位素效应出乎意料地大(约20%),这对脱脂率产生了明显的区分。根据动力学参数,空间动力学同位素效应和未氘代和氘代轮烷的1 H NMR光谱,我们提出了一种涉及预平衡的脱脂机理。
