Arylacetaldehydes were successfully synthesized by the anti-Markovnikov Wacker-type oxidation of vinylarenes using 1 atm O2 as a terminal oxidant under mild conditions. Electron-deficient alkenes, such as maleic anhydride and maleimides, were effective additives and would operate as ligands to stabilize the Pd(0) species during the reaction.
Catalytic oxidation of alkenes with a surface-bound metalloporphyrin- peptide conjugate

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 competition experiments demonstrated the ability of the conjugate catalyst to discriminate between substrates on the basis of size. Both results suggest oxidative catalysis occurred between the porphyrin ring and the peptide chain with the peptide influencing the outcome of the reaction in accord with the catalyst design.
