Cobalt-Catalyzed Oxidative Homocoupling of Arylzinc Species
A novel procedure for the synthesis of functionalized symmetrical biaryl compounds is described. The reaction proceeds via the oxidative homocoupling of arylzinc species formed by cobalt catalysis in the presence of air or p-benzoquinone depending on the nature of the functional group.

Nickel-catalyzed enantioselective arylation of pyridinium ions: Harnessing an iminium ion activation mode
A nickel for your thoughts.?? An enantioselective nickel-catalyzed cross-coupling between N-acylpyridinium salts and organozinc reagents is reported. The catalytic system, which is comprised of an air-stable NiII source and a chiral phosphoramidite ligand, affords 2-substituted-2,3-dihydro-4-pyridones with up to >99 % ee. Copyright

Cobalt-catalyzed electrophilic amination of arylzincs with N-chloroamines
Roles reversed: An efficient cobalt-catalyzed electrophilic amination of arylzinc reagents has been achieved. A variety of functionalized arylzincs and N-chloroamines were coupled under mild conditions (see scheme). Both secondary and tertiary arylamines were obtained in moderate to excellent yields.

Cobalt-catalysed synthesis of highly substituted styrene derivatives via arylzincation of alkynes
A new two-step procedure was developed by carbozincation of internal and terminal alkynes to synthesise highly functionalised vinylzinc bromides. Various tri and tetrasubstituted alkenes were prepared in moderate to good yields under mild reaction conditions in a stereo-selective manner. This methodology represents an interesting alternative to previously known methods. This journal is

New chemical synthesis of functionalized arylzinc compounds from aromatic or thienyl bromides under mild conditions using a simple cobalt catalyst and zinc dust
A new chemical method for the preparation of arylzinc intermediates is described in acetonitrile, on the basis of the activation of aryl bromides by low-valent cobalt species arising from the reduction of cobalt halide by zinc dust. This procedure allows for the synthesis of a variety of functionalized aryl- and thienylzinc species in good to excellent yields. The versatility and the simplicity of that original method represent an alternative to most known procedures.
