Self‐assembled metalloporphyrins–inorganic hybrid flowers and their application to efficient epoxidation of olefins

“…There are at least three reasons that strongly inspired us to choose metalloporphyrins as the organic building block. First, as a biomimetic model of cytochrome P450 enzyme, metalloporphyrins have received considerable attention due to their extremely high catalytic activity, especially in selective oxidation reactions, including olefin epoxidation, sulfides oxidation, alcohol oxidation, and Baeyer‐Villiger reaction . It can be expected that hybrid flowers composed of metalloporphyrins will show equally superior catalytic performance.…”

Synthesis of Metallo-Deuteroporphyrin Derivatives and the Study of Their Biomimetic Catalytic Properties

“…The largest bulk of reports have been with Mn(III), Fe(III), Ru(III), Co(III) and Cr(III) porphyrins, in that order. Among them, Mn(III), Fe(III), Ru(III) and Co(III) porphyrins have been found to be efficient catalysts for www.intechopen.com the mono-oxygenation of alkanes, the epoxidation of simple olefins and the oxidation of sulphides, while Cr(III) porphyrins be competent only for epoxidation Zhou et al, 2007). An enormous range of oxidants have been used as oxygen donors to the metalloporphyrins, including iodosobenzene, peroxyacids, hypochlorite, chlorite, hydroperoxides, N-oxides, hydrogen peroxide, monoperoxyphthalate, potassium monopersulfate and molecular oxygen (or air).…”

Rapid Synthesis of Alkyloxy Porphyrins Under Microwave Irradiation

“…[10] Recently we have found that metalloporphyins exhibited highly catalytic performance for oxidation of alkanes, [11] olefins, [12] sulfides, [13] alcohols, [14] and aldehydes [15] with molecular oxygen. However, the conventional synthesis of porphyrin and its derivatives [16] is time-consuming.…”
