reactions involving ionic-to-covalent bond transformation were achieved in the ionic molecular crystals of 1,8-bis[(pyridin-1-ium-1-yl)methyl]anthracene anthracene-1,8-dicarboxylate to produce the cyclic diester. The crystal structure given by X-ray diffraction analysis showed that the electrostatic interaction between the benzyl pyridinium cation and the carboxylate anion successfully works to locate these
在 1,8-双[(pyridin-1-ium-1-yl)methyl]anthracene anthracene-1,8-dicarboxylate 的离子分子晶体中实现了涉及离子到共价键转化的热固相反应,以产生环二酯。X 射线衍射分析给出的晶体结构表明,
苄基吡啶鎓阳离子和
羧酸根阴离子之间的静电相互作用成功地使这些反应位点彼此靠近,并且存在结晶溶剂和释放的
吡啶逃逸的通道。因此,通过晶体与晶体的反应选择性地形成了环二酯,这通过反应前后晶体的粉末 XRD 图谱和光学显微镜和
SEM 图像得到了证实。这是第一个热晶体对晶体的缩合反应。还研究了 1,8-双[(pyridin-1-ium-1-yl)methyl]
蒽蒽醌-1,8-二
羧酸盐的另一种离子分子晶体。其中,相应的环二酯也...
