Undirected/Directed Cross‐Coupling: A new dehydrogenative RhIII‐catalyzed cross‐coupling reaction between bromoarenes bearing no directing group and vinylic substrates substituted by a chelating group is reported. An original reaction mechanism enables the use of internal alkenes in a Z‐selective coupling. The application of 1,3‐disubstituted or 1,2‐homodisubstituted arenes leads to the formation of highly functionalized
无定向/定向交叉偶联:报道了不带导向基团的溴代芳烃与被螯合基团取代的乙烯基底物之间发生的新的脱氢Rh III催化的交叉偶联反应。原始的反应机理可以在Z选择性偶合中使用内部烯烃。1,3-二取代或1,2-同二取代的芳烃的应用导致形成高度官能化,复杂且有价值的烯烃作为一种单一异构体。
