✦ Synopsis

We report the first use of a nickel catalyst for the direct arylation of a b-difunctionalized compound, the malononitrile, from halogenated aromatic substrates. The catalytic system is quite simple: Ni(PPh 3 ) 3 , generated in situ from NiBr 2 (PPh 3 ) 2 , PPh 3 and zinc. Good yields and excellent selectivities have been obtained in a-arylmalononitriles from iodobenzene, but also from bromo-or chloro-aromatic substrates.
