Abstract

A sterically-hindered carbonylruthenium(II) porphyrin Ru-II(CO)(TMP) (where TMP = meso-tetramesitylporphyrinato dianion) has been synthesized. Chemical oxidation of Ru-II(CO)(TMP) by m-chloroperbenzoic acid (m-CPBA) gives the dioxoruthenium(VI) porphyrin (Ru-VI(O)(2)TMP). Cyclic voltammograms show that Ru-VI(O)(2)TMP is reversibly oxidized at E-1/2 = +1.24 V in CH2Cl2. Thin-layer absorption spectra for oxidation of Ru-VI(O)(2)TMP at + 1.32 V indicates that the product is a porphyrin cation radical (Ru-VI(O)(2)TMP+.). Electrogenerated Ru-VI(O)(2)TMP+. reacts selectively with styrene to give phenylacetaldehyde (96%) and benzaldehyde (4%). We report the first case of styrene oxidation by high valent ruthenium porphyrin under electrochemical conditions. An electrocatalytic oxidation reaction scheme is proposed.
