Selective Rhodium(III)‐Catalyzed Cross‐Dehydrogenative Coupling of Furan and Thiophene Derivatives

A hot couple: An unprecedented rhodium(III)-catalyzed cross-dehydrogenative coupling (CDC) of various furan and thiophene derivatives leads to valuable 2,2′-bi(heteroaryl) products in good yields and selectivities (see scheme). In addition, pyrroles and indoles can also be used as coupling partners, giving C3-arylated products.
