Benzhydroxamic acid is used as precursor in the synthesis of novel mono-anionic and di-anionic hydroxamato complexes by reacting with BiPh3 and Bi(O(t)Bu)3, which has anti-bacterial activity against helicobacter pylori. It is used in the photometric determination of trace amounts of vanadium in alloy steels by making mixed-ligand vanadium chelates with ammonium thiocyanate. It is also involved in the palladium catalyzed synthesis of benzisoxazolones.
Reaction with alkynes, catalyzed by NaH in DMSO, gives 2-phenyloxazoles: Can. J. Chem., 51, 1368 (1973).
Oxidation with tetraalkylammonium periodates generates the transient benzoylnitroso compound, which can react in situ with dienes to give good yields of cycloaddition products: Tetrahedron Lett., 4763 (1978); J. Chem. Soc., Perkin 1, 883, 887 (1985); J. Org. Chem., 50, 1911 (1985).
