Technical Notes:

1.An approach to five-me mbered lactams from aliphatic amides and terminal acetylenes by nickel catalysis.

2.Synthesis of biaryls through nickel-catalyzed Suzuki-Miyaura coupling of amides by carbon-nitrogen bondcleavage.

3.Ni-catalyzed borylation of aryl fluorides via C-F cleavage.

4.Nickel- and palladium catalyzed coupling of aryl fluorosulfonates with aryl boronic acids enabled by sulfurylfluoride.

5.Nickel-catalyzed one-pot synthesis of biaryls from phenols and arylboronic acids via c-0 activation using TcT reagents.
