  • Green Chemistry Catalysts #2 FINAL.mpg Metalloporphyrins can be robust catalysts for the selective oxidation of alkenes and other hydrocarbons. The catalytic activity of the metalloporphyrin depends on the nature of the central metal atom and the architecture of the porphyrin macrocycle. For example, functionalization on the periphery of the porphyrin macrocycle by halogen atoms is known to increase catalytic activity. Herein, we report the catalytic activity of nanoparticles of two different metalloporphyrin systems: 5,10,15,20-tetrakis-[4-(1'H,1'H,2'H,2'H-heptadecafluorodecane-1-thiol)-2,3,5,6-tetrafluorophenyl]porphyrinato iron(III), Fe(III)TPPF84, and 5,10,15,20-tetakis-(2,3,4,5,6-pentafluorophenyl) porphyrinato manganese(III), Mn(III)TPPF20, for the oxidation of cyclohexene using molecular oxygen as an oxidant and using an aqueous solvent under ambient conditions. While the solvated metalloporphyrins catalytically oxidize alkenes to the corresponding epoxide with a modest turn-over numbers (TON), 10-30 nm organic nanoparticles (ONPs) of these metalloporphyrins have enhanced catalytic activity with up to a 4-fold greater TON and yields only allylic oxidation products. The activity of ONPs is slow compared to the solvated metalloporphyrins. These ONP catalytic systems facilitate a greener reaction since ca. 89% of the reaction medium is water, molecular oxygen is used in place of man-made oxidants, and the ambient reaction conditions require less energy. This ONP catalytic system also avoids using ...
