Emerging Photoredox And Nickel Catalysis:Vinylation Of Phenylacetylenes

Alkyne is an important structure of biologically active compounds and organic photoconductive materials, and it is also important for organic synthesis. Olefins is an important class of chemistry, materials, mechanical engineering, biologically active compounds and natural products. How to synthesis the olefins you want with simple methods and It is a challenge the method can apply in chemical, material, the pharmaceutical industry.Light is a new energy source, attracted a lot of scientific work.Will light the green energy used in the chemical experiment is the pursuit of many chemists. In recent years, with the development of photochemical, scientific workers have been tried to put light and metal catalyst in a catalytic systems for synthesis of a variety of important chemical products.Emerging photorecatalysts and nickel catalyze vinylation of alkyne with diacyl peroxides a new reagent have been synthesised and used. A series of experiments of tris[(4,4’-Di-tert-butyl-2,2’-bipyridine)] ruthenium dichlorid hexahydrate and nickel chloride anhydrous catalyzed vinylation of Phenylacetylenes and diacyl peroxides with visible light have been employed.And the functional groups were tolerated in this reaction.Radical scavenger and control experiment were employed for studying mechanism.
