Proton-sponge behaviour of new pendant armed cross-bridged bis-cyclens: Synthesis, NMR, X-ray, and potentiometric investigations

Abstract

The synthesis via bis-aminal derivatives and proton-sponge behaviour of new constrained bis-cyclens in which each macrocyclic subunit is alkylated with an alcohol function is presented and highlighted with NMR spectra, X-ray data and corroborated by potentiometric investigations.
