Sphos (2-dicyclohexylphosphino-2′,6′-dimethoxy-1,1′- biphenyl) adduct of cyclopalladated ferrocenylimine (IIe) 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.

The key Pd-catalyzed cross-coupling of aryl bromides or triflates and cyclopropylmagnesium bromide in the presence of substoichiometric amounts of zinc bromide produces cyclopropyl arenes in good to excellent yields. The cross-coupling of other alkyl, cyc

The introduction of an unsubstituted cyclopropyl moiety was efficiently accomplished via Negishi cross-coupling of cyclopropylzinc bromide with functionalized aryl halides in high yields and fast reaction rates. The stability and the efficient one-step sy
