Cu-Catalyzed Synthesis of Symmetric Group 6 (Fischer) Bis-carbene Complexes
摘要:
The efficient copper oxidative homocoupling (CuCI/TMEDA/O-2) of alkynyl Fischer carbene complexes yields bis-carbene complexes having pi-tethers. The bimetallic complexes are exceptional templates to prepare diverse organic symmetric structures connected by pi-extended fragments.
