Cu-Catalyzed Synthesis of Symmetric Group 6 (Fischer) Bis-carbene Complexes

The efficient copper oxidative homocoupling (CuCl/TMEDA/O2) of alkynyl Fischer carbene complexes yields bis-carbene complexes having π-tethers. The bimetallic complexes are exceptional templates to prepare diverse organic symmetric structures connected by π-extended fragments.
