Synthesis of perfluoroalkylated benzenes and pyridines through cationic Rh(I)/modified BINAP-catalyzed chemo- and regioselective [2+2+2] cycloaddition

A convenient synthesis of perfluoroalkylated benzenes and pyridines has been achieved by a cationic Rh(I)/modified BINAP-complex-catalyzed chemo- and regioselective [2 + 2 + 2] cycloaddition of alkynes with a perfluoroalkylacetylene and a perfluoroalkylnitrile.
