Until the 196Os, complexation of alkali and alkaline earth metal cations was problematic.
Although such Ca2+ binders as ethylenediaminetetraacetic acid, EDTA, were well known …

The interaction of alkali metal ions with arenes such as benzene or substituted benzenes
has been documented in a variety of ways. This paper reviews the experimental evidence …

Nitrogen-pivot lariat ethers of varying ring sizes can be prepared by cyclization of an amine
or appropriately substituted diol. Twelve-membered-ring nitrogen-pivot lariat ethers were …

Cation-π interactions of alkali metals with arenes have been known in the gas phase for two
decades but solid-state structural data have become available only recently. The quest for …

The electrically neutral compounds (including solvents and crowns) have been denoted by
capital letters while the anions use lower-case letters; the crown-related macrocycles have …

X-ray crystal structure data are presented for K+ complexes of A'-allylmonoaza-18-crown-6
(1) monohydrate [K+ C 5-allyl-H20], 7V, 7V'-bis (3-oxabutyl) diaza-18-crown-6 (2)[K+ C1-22 …

Rangoon, Burma, and Calcutta, India, are somewhat unlikely places to begin a review of the
chemistry of tridentate and pentadentate macrocyclic complexes. However, in 1937 Peacock …

Eleven lipophilic bis (monoaza crown ether) derivatives [1 and 2 (= 0-3) and 3 (= 1-3)] were
synthesized, in which two monoaza crown ethers with 9-, 12-, 15-, or 18-membered rings are …

Novel spironaphthoxazine compounds with an aza-15-crown-5 ether fragment at position
5′ or 9′ of the naphthalene ring were synthesised. Spectrokinetic measurements showed …

Biomimetic approaches to naturally occurring ion transport were discussed. Selective
transport systems of alkali, alkaline earth, heavy, and transition metal cations as well as …
