Abstract

Abstract One-pot regioselective benzylation of pyrroles and indoles using zirconium tetrachloride is discussed. This has been achieved by in-situ generation of di (1H-pyrrol-1-yl) zirconium (IV) chloride and di (1H-indol-1-yl) zirconium (IV) chloride. It was observed that benzylation reactions of these complexes using n-BuLi occurred at C-2 position for pyrrole and C-3 for indole. Copyright© 2011 John Wiley & Sons, Ltd.
