A novel organic acid-base-co-catalyzed conversion of styrylepoxides into [1,1′-biaryl]-3-carbaldehydes was realized under microwave irradiation. Styrylepoxides first underwent an acid-catalyzed Meinwald rearrangement followed by a tandem base-catalyzed Michael addition, aldol addition, and aromatization sequence to generate [1,1′-biaryl]-3-carbaldehydes.

A highly general and selective Co-catalyzed biaryl coupling through C-F cleavage under phosphine or NHC-free conditions was described. A broad range of aryl fluorides including unactivated fluorides as well as those with sensitive functionalities could couple with various Ti(OEt)4-mediated aryl Grignard reagents with high selectivity under the catalysis of CoCl2/DMPU. Importantly, selective C-F bond activation couplings between two types of fluorines (difluorinated aromatics and on two different coupling partners) and in the presence of C-Cl or C-Br bonds could also be achieved.
