bimetallic RhII catalyst promoted the CH alkenylation of simple arenes at 1.0 equivalent without the use of a directing group. A phosphine ligand as well as cooperative reoxidation of RhII with Cu(TFA)2 and V2O5 proved essential in providing monoalkenylated products in good yields and selectivities, especially with di‐ and trisubstituted arenes.
双金属的Rh II催化剂促进与c H在1.0当量,而无需使用定向基团的简单的芳烃的烯基化。膦配体以及Rh II与Cu(TFA)2和V 2 O 5的协同再氧化被证明对于以高收率和选择性提供单烯基化产物至关重要,特别是对于二取代和三取代的芳烃。
