C(sp3)-H dehydrogenative cross-couplings of ethers, tetrahydrothiophenes, and pyrrolidines with alcohols were achieved under visible light irradiation by using iodobenzene and an in situ-formed gold complex. This method offers broad functional group compatibility and was successfully applied in late-stage modifications of bioactive molecules.
