The synthesis, conformational structure, electronic property, and anion complexation of novel coronarenes were systematically studied. A number of corona[4]arene[2]tetrazines that contain different combinations of nitrogen atoms with O, S, SO2, and CH2 as bridging units were synthesized conveniently by means of a fragment coupling strategy based on efficient nucleophilicaromaticsubstitution reaction

dibenzenethiols produced corona[4]arene[2]tetrazines that contain mixed oxygen, sulfide, methylene, and sulfone linkages. Macrocyclic ring transformations employing an inverse-electron-demand Diels–Alder reaction of tetrazine moieties with enamines and the subsequent sulfide oxidation reaction afforded diverse corona[4]arene[2]pyridazines. The acquired corona[6]arenes adopted three types of conformational

Corona[5]arenes, a novel type of macrocyclic compound that is composed of alternating heteroatoms and para‐arylenes, were synthesized efficiently by two distinct methods. In a macrocycle‐to‐macrocycle transformation approach, S6‐corona[3]arene[3]tetrazine underwent sequential SNAr reactions with HS‐C6H4‐X‐C6H4‐SH (X=S, CH2, CMe2, SO2, and O) to produce the corresponding corona[3]arene[2]tetrazines
电晕[5]芳烃是一种由交替的杂原子和对亚芳基交替组成的新型大环化合物,可通过两种不同的方法有效地合成。在从大环到大环的转化方法中,S 6-电晕[3]芳烃[3]四嗪与HS-C 6 H 4 -X-C 6 H 4 -SH进行顺序的S N Ar反应(X = S,CH 2,CMe 2,SO 2和O)生成相应的电晕[3]芳烃[2]四嗪。还可以通过HS-C 6 H 4的单锅三组分反应以直接的方式构建不同的电晕[3]芳烃[2]四嗪化合物‐X‐C 6 H 4 ‐SH(X = S,CH 2,CMe 2,SO 2和O)与2,5-二巯基对苯二甲酸二乙酯和2当量的3,6-二氯四嗪在非常温和的条件下。所有电晕[5]芳烃在晶体状态下均采用1,2,4-交替构象结构,产生相似的近乎规则的五边形腔。所获得的大环的腔尺寸和电子性质都通过桥接元素X的性质进行了微调。
