A new family of MnII complexes stabilized by carboxylate-rich hybrid ligands has been synthesized, characterized and applied as catalytic precursors for MnO2 nanoparticles in water oxidation by (NH4)2Ce(NO3)6.

Abstract We have developed a convenient solvent‐ and catalyst‐free selective Mannich reaction of a variety of para‐substituted phenols or catechols with paraformaldehyde and ethyl iminodiacetate. With para‐substituted phenols and electron‐poor catechol, only the monosubstituted benzyliminodiacetic ester is selectively formed in good yield and no disubstituted product is detected. In contrast, electron
