Proton coordination by polyamine compounds in aqueous solution

The present article is concerned with proton transfer reactions in aqueous solution of open-chain, macrocyclic and macropolycyclic or cage compounds h aving nitrogen atoms as protonation sites in the molecular framework, altho ugh several compounds with additional different donors will be considered. The main purpose of this review is to collect some significant examples of proton transfer processes in order to show how the electronic properties an d molecular topology of polyamines affect the thermodynamic parameters of t heir protonation equilibria.
