A novel surface-bound metalloporphyrin-peptide conjugate was prepared and used to catalytically oxidize alkenes in the presence of iodosylbenzene. The catalyst was found to oxidize a number of alkene substrates in good yield under a variety of reaction conditions. Comparison to control experiments using surface-bound Mn (III) tetraphenylporphyrin showed differences in oxidation yields and ratios of oxidized products. Substrate ...
