Abstract: In this research a new method for preparing Mn(III)-salen complexes from 1,3-oxazine compounds has been investigated. The ligands were synthesized from the Mannich condensation of 1,2-diamines (1,2-ethylenediamine or 1,2-cyclohexanediamine) with phenolic compounds (2-naphthol or 4-flourophenol)… read more here.
