Article abstract of DOI:10.1007/BF01671677

A potential boronate affinity chromatography ligand o-boronobenzalmethoxyamine (IV) and its precursor of the distinguishing functional group.In addition, 11B NMR data confirmed the lack of any coordination between the boron and oxygen atoms in the boronic acid compounds III and IV and the catachol ester derivative (V) of IV. o-Formylbenzeneboronic acid (III) crystallizes in space group P2₁/n with a = 3.883(1), b = 13.225(1), c = 14.029(2) Angstroem, β = 92.16(1) deg, and four molecules per unit cell. o-Boronobenzalmethoxyamine (IV) crystallizes in space group Pccn with a = 14.158(2), b = 17.156(1), c = 7.734(2) Angstroem, and eight molecules per unit cell.Selected bond distances and angles are tabularized.KEY WORDS: Boronate, o-Boronobenzalmethoxyamine,
