摘要：Several novel development-accelerator-releasing colorless couplers 2-[4-(2-acetylhydrazino)anilinocarbonylmethyl]thio-5-arylcarbonylmethylthio-1,3,4-thiadiazoles were synthesized by a simple and efficient three-step procedure starting from 2-ethoxycarbonylmethylthio-5-mercapto-1,3,4-thiadiazole 1- and 2-bromo-4'-substituted acetophenones. The structure of the compounds was confirmed by elemental analysis, MS, IR and H-1-NMR spectroscopy.
