## Abstract The dirhodium method has been successfully applied in chiral recognition of the optically active Schiff bases, derivatives of __ortho__‐hydroxyaldehydes existing in the NH‐form. or at tautomeric equilibrium. The position of the equilibrium of Schiff bases as well as their adducts has be

## Abstract Optically active Schiff bases, derivatives of **__ortho__**‐hydroxyaldehydes and their adducts with dirhodium tetracarboxylate complexes have been studied by ^15^N NMR spectroscopy. The position of the equilibrium of Schiff bases, as well as their adducts, has been established on the ba
