Title
Silica sulfuric acid a novel and heterogeneous catalyst for the synthesis of some new oxindole derivatives
Abstract

Silica sulfuric acid catalyzed efficiently the electrophilic substitution reaction of an indoles with various isatins in dicholoro methane to afford the corresponding oxindoles derivatives in high yields under r.t. The catalyst exhibited remarkable reusable activity.
