Abstract :b-Tetrabromo-meso-tetrakisinsert ignore into journalissuearticles values(4-methoxyphenyl);porphyrin, H2Tinsert ignore into journalissuearticles values(4-OCH3P);PBr4, was synthesized and characterized by UV-Vis and 1H NMR spectroscopy. Oxidation of alkanes and olefins with tetra-n-butylammonium peroxymonosulfate insert ignore into journalissuearticles values(n-Bu4NHSO5); was studied in the presence of MnTinsert ignore into journalissuearticles values(4-OCH3P);PBr4insert ignore into journalissuearticles values(OAc); and MnTPPPBr4insert ignore into journalissuearticles values(OAc); insert ignore into journalissuearticles values(TPP = meso-tetraphenylporphyrin);. While significance differences were observed between the catalytic activities of the title complexes in the oxidation of alkanes, the 2 manganese porphyrins showed comparable activities in oxidation of most of the olefins used. However, the latter showed greater catalytic performance in the oxidation of the hydrocarbons. Moreover, the oxidative degradation of the former insert ignore into journalissuearticles values(60 %); was greater than that of the latter insert ignore into journalissuearticles values(45 %); in the oxidation of cyclooctene.
