Abstract
1,3-Bis [3-(aryl)-5-(aryl) pyrazol-1-yl] propanes (2a-i) and 1,3-bis [ 2-(aryl) indol-1-yl] pro panes (4a,b) were prepared from appropriate 4 ,5dihydropyrazoles(1a-i) and 2-arylindoles (3a,b) respectively, via li quid-liquid phase transfer catalysis (PTC) using tetra-n-butylammonium hydrogen sulphate. Benzene was used as the organic phase and 50% KOH as the aq phase. The proposed structures for the products are establis hed on the basis of spectral (IR, PMR, Mass) and analytical data.
