Sphos (2-dicyclohexylphosphino-2',6'-dimethoxy-1,1'-biphenyl) adduct of cyclopalladated ferrocenylimine (Ile) exhibited highly catalytic activity for the Suzuki cross-coupling reaction of cyclopropylboronic acid with aryl(het) halides with 1 mol % catalyst loading. This process was applied to both of aryl and heteroaryl halides (Br and Cl), and made the various arylcyclopropane and heteroarylcyclopropane to be easily synthesized. A variety of substituents on the aryl halides, such as alkyl, acetyl, benzoyl, ether, formyl, carboxylate, methoxy, nitro and cyano were tolerated. (C) 2011 Elsevier Ltd. All rights reserved.
