 Title    Zur Kenntnis organischer Lewissäuren, 31 Die Lewissäureeigenschaft einiger Barbitursäurederivate * On Organic Lewis Acids, 31 Lewis Acid Properties of Some B arbiturates  
 Abstract    Arylidenbarbituric acids (4) and arylidendimethylbarbituric acids (5) are compounds w ith a polarized C = C-double bond, and hence are electrically neutral lewis acids. There­ fore they are able to add bases. The measured UV spectra show a characteristic dependence on the pH value. pK values are reported.
