Beschreibungen/Notizen

• Cobalt(II)‐catalyzed C(sp2)O cross‐coupling between aryl/heteroaryl alcohols and vinyl/aryl halides in the presence of CuI has been achieved under ligand‐free conditions. In this reaction, copper plays a significant role in transmetalation rather than being directly involved in the CO coupling. This unique Co/Cu‐dual catalyst system provides an easy access to a library of aryl–vinyl, heteroaryl–styryl, aryl–aryl, and heteroaryl–heteroaryl ethers in the absence of any ligand or additive. Raring to Co: The first application of a cobalt catalyst in the intermolecular C(sp2)O cross‐coupling of aromatic alcohols has been achieved in presence of a copper cocatalyst as transmetalating agent. This unique Co/Cu‐dual catalyst system provides easy access to a library of aryl–vinyl, heteroaryl–styryl, aryl–aryl, and heteroaryl–heteroaryl ethers in the absence of any ligand or additive.
