Abstract
Twenty N-arylhydroxamic acids, three of which contain a triple
bond in the side chain, have been synthesized and characterised by
elemental analysis, melting point, spectral characteristics in the
infrared region, and reaction with vanadium{V). All the N-arylhydroxamic
acids form chloroform extractable coloured complexes
with vanadium(V) in a strong hydrochloric acid medium. The use
of N-phenylphenylpropiolohydroxamic acid as reagent for vanadium(
V) by spectrophotometric method is described.
