Macrocyclic Receptor Molecules for Guanidinium Cations. Preparation, X-ray Structures, and Kinetic Stabilities of 1:1 Complexes of Guanidinium Perchlorate with Benzo-27-crown-9, Dibenzo-27-crown-9, and Dibenzo-30-crown-10

The complexation of guanidinium perchlorate with crown ethers of different ring size (18-33 ring atoms) and with different subunits, e.g., catechol and 1,3-xylyl moities, has been studied by using two-phase extraction experiments.The results demonstrate t
