BARBA, Victor; SANTILLAN, Rosa  e  FARFAN, Norberto. Dimeric Boronates Derived from the Reaction of Schiff Bases and Boronic Acids. J. Mex. Chem. Soc [online]. 2005, vol.49, n.2, pp.211-217. ISSN 1870-249X.

The one-pot synthesis of dimeric boron complexes is reported. The compounds were obtained by reaction of Schiff bases (tridentate ligands) with trans-β-phenylvinylboronic acid, 3-thiopheneboronic acid and methylboronic acid. Building of the dimeric structures is favored by the presence of intramolecular N→B coordination bonds, resulting in the formation of ten-membered ring heterocycles. An X-ray crystallographic analysis for one of them confirmed the dimeric nature of these compounds.
