This Ni(II)/Ni(IV) catalytic cycle with C–H bond activation mode is very different from previous nickel-catalyzed C(sp2)−H borylation processes that proceed through either a Ni(0)/Ni(II) catalytic cycle or nanoparticle catalysis22,23,24,25. Fig. 1: Nickel-catalyzed C(sp2)−H ...
Representative procedure for migratory allylic arylation of 1,n-enols enabled by nickel catalysis Under a nitrogen atmosphere, a mixture of Ni(cod)2(5.5 mg, 0.02 mmol), PCy3(11.2 mg, 0.04 mmol), Lewis acid (0.04 mmol), and ArB(OH)2(0.4 mmol) was added a solutio...

Dual nickel/photoredox catalysis, which combines nickel catalysis with photocatalysis, has emerged as an elegant and practical synthetic strategy for forging various carbon-carbon bonds and accomplishing the dicarbofunctionalization of a... H Wang,XU Tao - 《Chem Catalysis》 被引量: 0发表: 2024年 ...
ABSTRACT Difunctionalization of alkenes have developed into an important type of reactions for rapidly and effi-ciently assemble complex molecules.While extensive advancements have been achieved by the assistance of transition metal catalysis,the employment of cheap,abundant aryl chlorides as coupling partner...
As one of the most abundant metals on earth, iron is inexpensive, environmentally benign, and of low toxicity, and as such it is a fascinating alternative to the precious metals for catalysis and sustainable chemical manufacturing. However, iron catalysts have been undeveloped compared to other ...
Enantioselective nickel Lewis acid catalysis The aforementioned successful approaches commonly harness two catalysts, with one performing the photochemical activation and the other dictating the enantioselectivity. In addition to this dual nickel and photoredox catalysis platform, the catalytic system that uses...
