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.

The bis(acetonitrile)palladium(II) chloride complex, PdCl2(MeCN)2, efficiently catalyzes the regioselective alkylation of indoles with various benzylic and allylicalcohols under moisture and air insensitive conditions. Notably the reaction does not require any other co‐catalyst, acid, base, additive, or external ligand.
