The heterobimetallic catalyst [Pd(COD)Cl-SnCl3] efficiently promotes the intermolecular hydroarylation of alpha-methyl substituted arenes (otherwise known to be dimerized/polymerized in presence of Lewis Acids) with indoles and other O-, S-heteroarenes leading to Markovnikov adducts. The reaction takes place under air and moisture insensitive condition. (C) 2012 Elsevier Ltd. All rights reserved.
