冠醚类环状结构的配位体与重氮正离子形成络离子时,络合效应能增强重氮离子的稳定性,并能增大重氮盐在非极性溶剂中的溶解度.这种络合效应为重氮盐的有机反应创造了更为有利的条件.近十年来,人们合成了一系列的对位取代苯重氮盐的冠醚络合物,并对这类络合物的稳定性、电子结构以及它们在非极性溶剂中的溶解性及其机理进行了大量的研究.本文的工作是为了开展重氮盐冠醚络合物的电子结构及其稳定机理,合成了联苯双重氮氟硼酸盐二苯并—18—冠—6络合物.该络合物尚未见文献报道.
When the ligands of the crown ether ring structure form complex ions with the diazonium cation, the complexing effect can enhance the stability of the diazonium ion and increase the solubility of the diazonium salt in the non-polar solvent. The complexation effect has created more favorable conditions for the organic reaction of diazonium salt.A series of crown ether complexes of para-substituted benzene diazonium salts have been synthesized in the past ten years, Stability, electronic structure and their solubility in non-polar solvents and their mechanism of a lot of research.This work is to carry out the diazonium salt crown ether complex electronic structure and its stability mechanism, the synthesis of a joint Benzene diazoborate dibenzo-18-crown-6 complex has not been reported in the literature.
