Abstract

The reactivity against OH^−^ ion of some novel Fe(II) complexes of Schiff base ligands derived from salicylaldehyde or o‐hydroxynaphth‐aldehyde and some variety of amino acids has been examined in aqueous and aqua‐ethanol mixtures. The rate law and relevant mechanism were assumed. Base hydrolysis kinetics measurements revealed pseudo‐first‐order doubly stage rates because of the presence of mer‐ and fac‐isomers. The evaluated rate constants and activation parameters are consistent with the stability constants of the investigated complexes. © 2002 Wiley Periodicals, Inc. Int J Chem Kinet 34: 595–602, 2002
