摘要：

4,5-Dihydro-3,5-diaryl-1-(4-fluorophenylsulphonyl)-pyrazoles (2a-d) and 2-aryl-1-(4-fluorophenylsulphonyl)-indoles (4a-e) were prepared from 4-fluorophenylsulphonyl chloride and appropriate 4,5-dihydro-3,5-diarylpyrazoles (1a-d) and 2-arylindoles (3a-e) respectively, via solid-liquid phase transfer catalysis (PTC) using tetra-n-butylammonium hydrogen sulphate (TBAHSO(4)). THF was used as liquid phase and dry powdered KOH as solid phase. All the prepared compounds are characterized by their elemental and spectral (IR, PMR, Mass) analyses.
