A hydrogen atom transfer (HAT) step from acetone allowed the smooth generation of acetonyl radical that was then exploited as synthon in the mild formation of C–C bonds under flow conditions. The process was promoted by aryl radicals photocatalytically generated via single-electron transfer (SET) reduction of arenediazonium salts. The mechanism has been investigated by a combined experimental and computational approach and further supported by deuterium labeling experiments.

Abstract

A hydrogen atom transfer (HAT) step from acetone allowed the smooth generation of acetonyl radical that was then exploited as synthon in the mild formation of C–C bonds under flow conditions. The process was promoted by aryl radicals photocatalytically generated via single-electron transfer (SET) reduction of arenediazonium salts. The mechanism has been investigated by a combined experimental and computational approach and further supported by deuterium labeling experiments.

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.
