The Protonation Equili rium and Decomposition of Amino- and Hydroxyphosphonates, Phos phine Ox ides and Phosphonic Acid

Protonation states of amino and hydroxyl phosphoroorganic derivatives have been studied. Based on the presented calculations we can state that mono- and di-protonated species on nitrogen are dominating states in solution. The protonation on phosphoryl oxygen occurs only as an effect of dynamic equilibrium between protonated species. The double and tripple protonation lead to very strong acid and thus such states are rather not present even in strong acidic media.
