摘要
A method for the construction of various thio-bridged compounds is developed using readily available o-(trimethylsilyl)aryl triflates as a source of aryne precursor, catalyzed by simple Pd(dba)(2)/dppe complex. This operationally simple and modular protocol allows thio-bridged compound via C(sp(2) )-C(sp(2)) and C(sp(2))-C(sp(3)) bond formation in promising yields with a broad substrate scope. The key part is in situ generation of an aryne from o-(trimethylsilyl)aryl triflates and their subsequent intermolecular annulation. [GRAPHICS] .
