Ten new 1 aryloxyacetyl 4 (2 nitrobenzoyl) thiosemicarbazides(Ⅲ) were synthesized under the condition of solid liquid phase transfer catalysis, and compounds Ⅲ on further reaction with acetic acid gives ten 2 (2 nitrobenzoylamido) 5 aryloxymethyl 1,3,4 thiadiazoles(Ⅳ). Compounds Ⅲ and Ⅳ were characterized by elemental analysis, IR and 1H NMR. The preliminary promoting effects of compounds Ⅲ and Ⅳ on wheat growth were also tested.
