文摘

Using the flytrap approach, paramagnetic ansa-metallocenes of the late transition metals cobalt and nickel containing a tetra-tert-butyldistannane bridge have been prepared. The complexes were identified using a combination of analytical methods (NMR, EPR, cyclic voltammetry, and X-ray crystallography) and further converted to their corresponding cations by one-electron oxidation with ferrocenium hexafluorophosphate. Spectral and structural analyses of the ionic products are consistent with metal-based oxidations.
