Twenty years ago, the syntheses of N-(p-substitutedbenzalamino)oxindoles were conducted with the intention of correlating Hammett constants with the NMR shift of the iminyl proton. Sixteen different functional groups were substituted at the para position of the benzalamino entity and purified samples were sent out for NMR analysis. Now, this synthesis is being carried out again and the derivatives are being analyzed for FTIR, NMR, UV, fluorescence, and possibly phosphorescence spectral properties.
