| Abstract: | Benzoylben2o-15-crown-5 has been Synthesized by acylation in polyphosphoric acid(PPA) and then it reacts with thiosemicarbazide and semicarbazide under the acid condition to synthesize 4'-Acylsemicarbazonyl Thiourea and semicarbazone B15(5(alyl=c-ph). three new products was chracterized by elemental analysis,IR .and mass spectrometny. |
