Reported herein is an efficient synthetic protocol to ortho-functionalized 2-aryl thiophenes via Rh(III)-catalyzed C-H/C-H cross coupling of benzylthioethers or benzylamines with thiophenes. Both ortho- and meta-substituted benzylthioethers give monoheteroarylated products, while ortho-unhindered substrates mainly provide diheteroarylated benzylthioethers. The C-H/C-H cross coupling of benzylamines with thiophenes exclusively generates diheteroarylated benzaldehydes. Mechanistic investigation discloses a three-step tandem process involving the ortho-C-H diheteroarylation of benzylamine, the oxidation of benzylamine to imine, and the hydrolysis of imine to aldehyde.
