A novel copper-catalyzed decarboxylative oxyalkylation of alkynyl carboxylic acids with ketones and alkylnitriles via direct C(sp3)–H bond functionalization to construct new C–C bonds and C–O double bonds was developed. This transformation is featured by wide functionalgroup compatibility and the use of readily available reagents, thus affording a general approach to γ-diketones and γ-ketonitriles
