Dioxovanadium(v) complexes with side chain substituted N-salicylidenehydrazides modelling supramolecular interactions in vanadium haloperoxidases

The water soluble ammonium salts of cis-dioxovanadium(v) complexes with side chain functionalized N-salicylidenehydrazides show hydrogen bonding interactions relevant for haloperoxidase enzymes. Under turnover conditions for the catalytic bromination of trimethoxybenzene, no substitution of the side chain hydroxy group is observed.
