Abstract: A novel copper-catalyzed arylation strategy for propargylsilanes utilizing diaryl-λ3-iodanes has been developed, enabling a cascade sequence involving 1,2-silyl migration and heterocyclization. The β-silicon effect facilitates the formation of stabilized allyl cation intermediates that undergo regioselective… read more here.
