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 functional group compatibility and the use of readily available reagents, thus affording a general approach to γ-diketones and γ-ketonitriles
通过直接的C(sp 3)-H键官能化来构建新的C-C键和C-O双键的新型铜催化的炔基羧酸与酮和烷基腈的脱羧氧化烷基化反应得到了发展。这种转变的特征是广泛的官能团相容性和易于使用的试剂的使用,从而为γ-二酮和γ-酮腈提供了一种通用方法。提出了一种可能的机制。
