Abstract

Together with a further improvement of the synthesis of (cyclopentadienyl)trioxorhenium(VII), CpReO3, its reaction chemistry and catalytic activity is also revisited in greater detail. However, in spite of the high catalytic activity of the homologous methyltrioxorhenium(VII) (MTO) and the related CpMo(O2)X, (X = R, Hal, etc.) it is seen that CpReO3 suffers greatly from the lability of the Cp-Re bond under oxidative conditions and in the presence of electron donor ligands. (Cyclopentadienyl)trioxorhenium(VII) although accessible very conveniently, neither matches the rich reaction chemistry of its pentamethylcyclopentadienyl derivative, Cp*ReO3 nor the catalytic versatility of MTO.
