Synthesis of boronate ester compounds via condensation reactions using either an amine or an amine N-oxide coupled with a boronic acid. Synthesis of boronate ester compounds using quinoline isomers coupled with 2, 3-dihydroxynaphthalene was also attempted. These compounds form B-N dative bonds, and potentially form macrocycles capable of trapping a guest molecule in the cavity. The exact sizes of the complexes are unknown at this time. Characterization of these compounds was performed by 1H NMR, FT-IR, mass spectroscopy, and 13C NMR.
