摘要
An alternative approach to formation of a C—C bond at a meta-position of an aromatic compound is disclosed that employs an ethylenically unsaturated bicyclic compound as a transient mediator to achieve meta-selective C—H activation with a simple and common ortho-directing group. The use of a pyridine-based ligand assists in relaying the palladium catalyst to the meta-position by the unsaturated bicyclic compound following initial ortho-C—H activation.
