substrates at elevated temperatures. Herein, we report a protocol for electrochemical C(sp2)–H/O–H cross-dehydrogenativecoupling of phenols and tertiary anilines to synthesize diaryl ethers. The C(sp2) H/O–H coupling product can be obtained under metal- and oxidant-free conditions at roomtemperature in moderate to excellent yield (up to 83% yield) with high regioselectivity (>99% for para-substitution)
