Molecular Inclusion Crystals of Novel Heterocyclic Host Compounds
摘要:
Inclusion phenomena of the solvents such as hexane, benzene, and dichloromethane in either the crystals or glassy states of the armed-1,4,8,12-tetrazacyclopentadecanes were observed, whereas only few inclusion was found in the armed 1,4,8,11-tetraazacyclotetradecanes. As further examples of undesigned inclusion hosts, the 1:2 adduct, obtained by Diels-Alder reaction of [2.2]paracyclophane with 4-phenyl-1,2,4-triazoline-3,5-dione, along with the 1:2 adducts from 5-cyano-1,4-diphenylpyridazino[4,5-a]-indolizines and dimethyl acetylenedicarboxylate (DMAD) are described.

A variety of new armed cyclopolyamines were prepared by high pressure SNAr reactions (0.8 GPa, 100 degrees C) of cyclopolyamines with heteroaromatic halides. Certain of these agents show selective extraction properties for Hg2+ and Ag+ ions.
