Alkyl aryl ketones are important structures with applications in many areas of chemistry. Hence, efficient procedures for their production are particularly attractive. In this communication, a general and efficientcarbonylative cross‐coupling of aryl iodides and unactivated alkyl bromides is presented. By using a simple palladium catalyst, a series of alkyl aryl ketones were synthesized in moderate

Three′s company: The selective α‐arylation and α‐arylativeesterification of linear and branched aldehydes is reported for a variety of bromoarenes. The acylation of arylbromides can be achieved with linear aldehydes (see scheme). All these transformations were performed with a single [(N‐heterocyclic carbene)Pd] catalyst through adjustment of the stoichiometry of the reagents and the appropriate

Ketones, as essential functional group skeletons, have garnered significant interest due to their diverse transformations. Herein, we describe a versatile photoredox catalyzed deacylation-aroylation strategy that enables the direct transformation of alkyl ketones to aryl ketones. This process involves photoredox deacylation of dihydroquinazolinones derived from alkyl ketones to generate alkyl radicals
