Recyclable graphite oxide catalyzed Friedel–Crafts addition of indoles to α,β-unsaturated ketones
摘要:
The Friedel-Crafts addition of indoles to alpha,beta-unsaturated ketones, and nitro styrenes was studied with graphite oxide as catalyst. Various indole derivatives were synthesized in good to excellent yields. The preparation of graphite oxide catalyst from simple and readily available starting materials makes this method more affordable. The heterogeneous graphite oxide can be easily recovered and recycled up to five cycles without loss of activity. (C) 2011 Elsevier Ltd. All rights reserved.
