An applicable and easy-handling Ni-catalyst can be used to promote direct arylation of α-bromonitriles with various arylboronic acids to construct α-arylnitriles under mild conditions. The methodology tolerates β-hydrogens and functional groups in the substrates.

interesting polycycliccompounds have been synthesized from non‐conjugated diyne systems by dualgoldcatalysis. A quaternary carbon center in the backbone and the accompanying Thorpe–Ingold effect enabled the unprecedented insertion of sp3 and sp2 CH bonds that for the first time were incorporated within the backbone of the diyne system and allowed the construction of complex polycyclic carbon scaffolds
