Acyl radicals were smoothly generated from acylsilanes under photoredoxcatalyzed conditions. These radicals were formed upon ultraviolet B (UV-B), solar, or visible light irradiation by using decatungstate and acridinium salts as photocatalysts. Acylation of Michael acceptors and a few styrenes resulted in a smooth preparation of unsymmetrical ketones in yields up to 89%.

Abstract

Acyl radicals were smoothly generated from acylsilanes under photoredoxcatalyzed conditions. These radicals were formed upon ultraviolet B (UV-B), solar, or visible light irradiation by using decatungstate and acridinium salts as photocatalysts. Acylation of Michael acceptors and a few styrenes resulted in a smooth preparation of unsymmetrical ketones in yields up to 89%.

The Organic Chemistry/Polymer Science category includes resources concerned with the related fields of organic chemistry and polymer science. The organic chemistry resources deal with compounds of carbon with the exception of certain simple ones, such as the carbon oxides, carbonates, cyanides and cyanates (see Inorganic & Nuclear Chemistry). This category includes research on synthetic and natural organic compounds that may include other elements, such as hydrogen and oxygen, but also nitrogen, halogens, sulphur and phosphorous. Resources concerned with hydrocarbons, organic compounds containing only the elements carbon and hydrogen, are also included in this category. Examples are the alkanes, alkenes, alkynes and aromatics, such as benzene and naphthalene. Polymer science includes all resources dealing with the study, production and technology of polymers, which are compounds composed of very large molecules made up of repeating molecular units (monomers). Polymers may be natural substances, such as polysaccharides or proteins, or synthetic materials, such as nylon or polyethylene.
