Ni-Catalyzed Sonogashira Coupling of Non-activated Alkyl Halides: Orthogonal Functionalization of Alkyl Iodides, Bromides, and Chlorides

Xile Hu, Oleg Vechorkin, Valérie Proust, Delphine Barmaz

Ni-catalyzed Sonogashira coupling of nonactivated, β-H- containing alkyl halides, including chlorides, is reported. The coupling is tolerant to a wide range of functional groups, including ether, ester, amide, nitrile, keto, heterocycle, acetal, and aryl h ...

Functional group tolerant Kumada-Corriu-Tamao coupling of non-activated alkyl halides with aryl and heteroaryl nucleophiles: Catalysis by a nickel pincer complex permits the coupling of functionalized Grignard reagents

Xile Hu, Oleg Vechorkin, Valérie Proust

A nickel(II) pincer complex [(MeNN2)NiCl] (1) catalyzes Kumada−Corriu−Tamao cross coupling of nonactivated alkyl halides with aryl and heteroaryl Grignard reagents. The coupling of octyl bromide with phenylmagnesium chloride was used as a test reaction. Us ...

Nickel Complexes of a Pincer NN2 Ligand: Multiple Carbon-Chloride Activation of CH2Cl2 and CHCl3 Leads to Selective Carbon-Carbon Bond Formation

Rosario Scopelliti, Xile Hu, Oleg Vechorkin

A new pincer-type bis(amido)amine (NN2) ligand and its lithium and nickel complexes, including Ni(II) methyl, ethyl, and phenyl complexes, were synthesized. The Ni(II) alkyl complexes react cleanly with alkyl halides including chlorides to form C−C coupled ...
