Nickel catalyzed one pot synthesis of biaryls under air at room temperature [PDF]

open access: yes, 2013
A practical, room temperature catalytic system has been developed for the synthesis of biaryls in one step from the homocoupling of in situ generated Grignard reagents using the nickel(II) complex.

Nickel binding sites in histone proteins [PDF]

open access: yes, 2012
Nickel compounds are well known as human carcinogens, though the molecular events that are responsible for this are not well understood. It has been proposed that a crucial element in the mechanism of carcinogenesis is the binding of Ni(II) ions within

Synthesis and Characterization of Three-Coordinate Ni(III)-Imide Complexes [PDF]

open access: yes, 2011
A new family of low-coordinate nickel imides supported by 1,2-bis(di-tert-butylphosphino)ethane was synthesized. Oxidation of nickel(II) complexes led to the formation of both aryl- and alkyl-substituted nickel(III)-imides, and examples of both types ...
