title: Poly(ruthenium carbonyl spirobifluorenylporphyrin): a new polymer used as a catalytic device for carbene transfer.
abstract: Oxidative electropolymerization of tetraspirobifluorenyl porphyrin ruthenium(II) carbonyl complexes can be used to coat Pt electrodes with polymeric films; after being removed from the electrode, these polymeric materials are able to catalyze the heterogeneous cyclopropanations and 2,3 sigmatropic rearrangements with ethyl diazoacetate.
