title: Decarbonylative C-C bond-forming reactions of saccharins by nickel catalysis: homocoupling and cycloaddition.
abstract: Decarbonylation of saccharins by nickel catalysis enables two kinds of CC bond-forming reactions; homocoupling of saccharins to form biaryls and cycloaddition with alkynes to form benzosultams. The former represents the first reported nickel-catalyzed decarbonylative CC homocoupling reaction, whereas the latter constitutes a powerful method to pharmaceutically relevant benzosultams. The reactions proceed with good functional-group tolerance and excellent regioselectivity.
