Synthesis of 1′,1‴-bis(heterocyclyl)biferrocene compounds
摘要:
A new method for preparing 1',l " ' -disubstituted heterocyclylbiferrocene derivatives via stepwise Stille coupling reaction of 1,1'-bis(tributylstannyl)ferrocene with heterocyclic bromides and subsequent Cu-catalyzed homocoupling reaction is established.
