Abstract
The synthesis and properties of eight new hydroxamic acids derived fro m alpha-phenylstyrylacrylic acids are described. These hydroxamic acid s, which are crystalline compounds, were characterized by their ultrav iolet, infrared, and NMR spectra. The purity was checked by HPLC and H PTLC. The nonaqueous titrations and alkaline hydrolysis are reported. Thermodynamic ionization constants at (25 and 35 +/- 0.1) degrees C ar e determined. Preliminary studies show that these acids form a chlorof orm-extractable violet complex with vanadium(V) in 6 M hydrochloric ac id solutions.
