建立了Cu（OAc）2/DDQ/DTBP/Py体系催化易得的烷基芳香族化合物与硅烷的氧化还原硅烷化-烯化串联反应。以良好至高产率提供了各种官能化的烯基有机硅化合物，具有总β-（E）选择性。对照实验表明，转化可能通过自由基途径进行。
Summary of main observation and conclusionA Cu(OAc)2/DDQ/DTBP/Py system catalyzed oxidative dehydrogenative silylation‐alkenation tandem reaction of readily available alkyl aromatic compounds with silanes was established. A variety of functionalized alkenyl organosilicon compounds were provided in good to high yields with a total β‐(E) selectivity. The control experiments revealed that the transformation might proceed through a radical pathway.
