A Facile Route to 1-Trifluoromethyl-2,3,4,5-tetramethylcyclopentadienyl Ruthenium Half- and Mixed-Sandwich Compounds
摘要:
A series of half and mixed-sandwich (Cpdouble dagger = 1-trifluoromethyl-2,3,4,5-tetramethylcyclopentadienide) ruthenium compounds have been synthesized from a new Cpdouble daggerRu synthon, [Cpdouble daggerRu(NCCH3)(3)](PF6). [Cpdouble daggerRu(NCCH3)(3)](PF6) is efficiently generated by photolysis of [Cpdouble daggerRuBz](PF6) in acetonitrile with a quantum yield of approximately 0.34. The methods described here should be useful for the synthesis of other compounds that contain the Cpdouble daggerRu group.
