| Abstract: | Under grinding and solvent-free conditions via a one-pot procedure, the reaction of 2-benzofuroyl chloride with ammonium thiocyanate and aryloxyacetetic acid hydrazide afforded 1-aryloxyacetyl-4-(2-benzofuroyl)-thiosemicarbazide. Not isolating, the resulting thiosemicarbazides were further ground with HIO4·H2O to give a series of new 1-aryloxyacetyl-4-(2-benzofuroyl)-semicarbazides in high yields. Structures of compounds are confirmed by elemental analyses and IR and 1H NMR spectra. |
