A silver catalyzed decarboxylative C(sp2)–C(sp3) coupling of vinylic carboxylic acids with alcohols, alkylbenzenes, cycloalkanes and cyclic ethers was developed by using DTBP as an oxidant. This reaction tolerates a wide range of substrates, and products are obtained in good to excellent yields. The reaction also shows good stereoselectivity, and only trans-isomers are obtained. In addition, a radical
通过使用DTBP作为氧化剂,开发了乙烯基羧酸与醇,烷基苯,环烷烃和环醚的银催化脱羧C(sp 2)-C(sp 3)偶联反应。该反应可耐受多种底物,并且以良好至极好的产率获得产物。该反应还显示出良好的立体选择性,并且仅获得反式异构体。此外,自由基途径将参与促进这种脱羧的C(sp 2)–C(sp 3)偶联反应。
