Cross-coupling reactions for carbon-carbon and carbon-heteroatom bond formation are of great importance in modern chem. synthesis. In addition to classical cross-couplings involving preformed or preactivated coupling partners, more recently breakthroughs have been made in the selective, direct coupling of abundant aliphatic carbon-hydrogen bonds using hydrogen atom transfer reactions in which the bond-dissociation energy is the thermodn. driving force. The more challenging carbon-carbon bond activation is still rather underdeveloped due to the bond inertness. Herein, we report a mild and general strategy for the activation of a diverse set of readily available cyclic alcs. for the remote and site-specific arylation of ketones via the combination of photoredox-mediated multisite concerted proton-electron transfer (MS-PCET) and nickel catalysis. The current cross-coupling proceeds with the generation of an alkoxy radical utilizing bond-dissociation free energy (BDFE) as the thermodn. driving force. Subsequently, the resulting remote carbon-centered radicals formed by C-C cleavage merge with the nickel catalytic cycle to create the challenging C(sp3)-C(sp2) bonds.
After consulting a lot of data, we found that this compound(29046-78-4)Reference of Nickel(II) chloride ethylene glycol dimethyl ether complex can be used in many types of reactions. And in most cases, this compound has more advantages.
