Herein, direct unreactive C-N borylation of aromatic amines by a photocatalyst was achieved. The C-N borylation of aromatic amines with bis(pinacolato)diboron (B2pin2) proceeded using a pyrene catalyst under light irradiation to afford desired borylated products and aminoborane as a byproduct. The yield of the borylated product improved under a CO2 atmosphere which probably reduced the inhibitory effect of aminoborane. Mechanistic studies suggested that the C-N bond cleavage and C-B bond formation proceeded via a concerted pathway.
Pd-catalyzed cross-coupling of highly sterically congested enol carbamates with grignard reagents via c-o bond activation

The palladium-catalyzed cross-coupling reaction of enol carbamates to construct highly sterically congested alkenyl compounds is presented for the first time. This protocol demonstrates the potential of using thermally stable and highly atom-economic enol electrophiles as building blocks in bulky alkene synthesis. This reaction accommodates a broad substrate scope with excellent Z/E isomer ratios, which also provides a new synthetic pathway for accessing Tamoxifen.

Amido pincer nickel complexes {Ni(Cl)[2-P(Ph2)C 6H4NC(Ph)=NAr]} (Ar = 4-MeC6H4, 1; Ar = 4-ClC6H4, 2; Ar = 4-MeOC6H4, 3) were shown to efficiently catalyze the cross-coupling of activated, unactivated, and deactivated aryl chlorides, N-heteroaryl chlorides, 1,4-dichlorobenzene, and vinyl chlorides with aryl Grignard reagents.
