STUDY OF THE ALKYLATION REACTIONS OF ISATIN UNDER LIQUID-SOLID PHASE TRANSFER CATALYSIS CONDITIONS USING LONG CHAIN ALKYL BROMIDES

Abstract

In this current work we report the alkylation reactions of isatin by long carbon chain alkyl bromides under liquid-solid phase transfer catalysis (PTC) conditions. The structures of 1-alkyl-indoline-2,3-diones obtained were elucidated on the basis of spectral data ( 1 H NMR, 13C NMR, IR and mass spectrometry). Moreover their structures were confirmed by the single-crystal X-ray diffraction studies.
