Preparing Mn(<scp>iii</scp>) salen-type Schiff base complexes using 1,3-oxazines obtained by Mannich condensation: towards removing ortho-hydroxyaldehydes

Abstract

Synthesis of Mn(<sc>iii</sc>)-salen type Schiff base complexes from 1,3-oxazines obtained from Mannich condensation. This method eliminates the restrictions on the use of<italic>ortho</italic>-hydroxyaldehydes.
