Abstract:
The structures of new compounds containing Zn II ions and Hdpa (2,2′‐dipyridylamine)‐chelating ligands were determined. The Hdpa chelating ligands coordinate to Zn II ions to form mononuclear units ( 1 and 5 ), and intermolecular nonclassical hydrogen‐bond (C–H ··· O or N/C–H ··· I) interactions generate polymeric compounds. The chelating ligands with a bipyridyl moiety form mostly mononuclear complexes of different types (I, II and III), and the combination of this ligand with a sulfate anion can produce polymeric species (Type IV). Interestingly, homogeneous catalyst 1 catalyzed efficiently the transesterification of a variety of esters with different alcohols, and hydrogen‐bonded polymer 5 showed the heterogeneous catalytic activity for the transesterification reactions. Preliminary selectivity test of primary over secondary alcohol protection in the presence of 1 provided, exclusively, the primary acetate, which suggests the potential utility of this catalyst to be selective for primary alcohols.(© Wiley‐VCH Verlag GmbH & Co.
