An efficient Cu-catalyzed C–H alkenylation with acyclic and cyclic vinyl boronates was realized for the first time under mild conditions. The scope of the vinyl borons and the compatibility with functional groups including heterocycles are superior than Pd-catalyzed C–H coupling with vinyl borons, providing a reliable access to multisubstituted alkenes and dienes. Subsequent hydrogenation of the product
在温和条件下,首次实现了具有无环和环状硼酸乙烯基酯的高效Cu催化的CH链烯基化。乙烯基硼的范围以及与包括杂环在内的官能团的相容性均优于Pd催化的CH-H与乙烯基硼的偶联,为多取代烯烃和二烯的可靠获得提供了条件。随后从内部乙烯基硼中氢化产物将导致仲烷基的安装。
