摘要：

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. (c) 2006 Elsevier B.V. All rights reserved.
