Pd-catalyzed oxidative cross-coupling between two electron rich heteroarenes
The transition-metal-catalyzed oxidative cross-coupling between two coupling partners with similar structure and electronic characteristics remains a challenge owing to difficulty in suppressing undesired homo-couplings. We herein report a Pd-catalyzed oxidative cross-coupling between two thiophenes under mild reaction conditions. This approach can also be extended to furans. Some notable advantages
