P,N,N-Pincer nickel complexes [Ni(Cl){N(2-R2PC6H 4)(2′-Me2NC6H4)}] (R = Ph, 3a; R = Pri, 3b; R = Cy, 3c) were synthesized and their catalysis toward the Kumada or Negishi cross-coupling reaction of aryl fluorides and chlorides was evaluated. Complex 3a effectively catalyzes the cross-coupling of (hetero)aryl fluorides with aryl Grignard reagents at room temperature. Complex 3a also catalyzes the cross-coupling of (hetero)aryl chlorides and arylzinc reagents at 80 °C with low catalyst loadings and good functional group compatibility. the Partner Organisations 2014.

4,4'-Unsymmetrically substituted biphenyls can be synthesized by cross-coupling reactions of substituted aromatic organometallic reagents and aromatic halides catalyzed by palladium complexes.This two-step method from commercially available aromatic halides has been used for the synthesis of a series of donor/acceptor para-substituted biphenyls, D-C6H4-C6H4-A, where D is an electron donor group and A an electron acceptor group, which are of interst as liquid crystal precursors and as having potential in non-linear optics.Biaryls in which the donor-phenyl moiety is replaced by a 2-furyl or 2-thienyl can be synthesized similarly.The method can also be used for the convergent synthesis of previously unreported unsymmetrically substituted polyparaphenylenes D-(C6H4)n-A (n = 3, 4).
