So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.VanAtta, Reuel B.; Franklin, Catherine C.; Valentine, Joan Selverstone researched the compound: Iron(III) trifluoromethanesulfonate( cas:63295-48-7 ).Application In Synthesis of Iron(III) trifluoromethanesulfonate.They published the article 《Oxygenation of organic substrates by iodosylbenzene catalyzed by soluble manganese, iron, cobalt, or copper salts in acetonitrile》 about this compound( cas:63295-48-7 ) in Inorganic Chemistry. Keywords: epoxidation olefin iodosylbenzene mechanism; metal nitrate triflate catalyst epoxidation. We’ll tell you more about this compound (cas:63295-48-7).
Reaction of PhIO with (Z)- (I) and (E)-stilbene (II), Me2C:CMe2 or cyclohexene in the presence of catalytic amounts of metal nitrates and triflates (metal = Fe2+, Fe3+, Mn2+, Cu2+) gave epoxidation in moderate to high yields. The same systems oxidize cumene to PhCMe2OH in moderate yields. All of the metal salt-PhIO reactions with II gave 16-86% I oxide, while reactions with I gave mixtures of II 0-82, I oxide 0-51%, and II oxide 4-51%. Some cleavage products were also observed Qual. comparisons of the epoxidation of the stilbenes catalyzed by M(O3SCF3)3 (M = Fe, Mn) with those catalyzed by the same metal porphyrins showed that the yields of the triflate- and porphyrin-catalyzed reactions were comparable for each metal ion. The triflates react more rapidly with II than with I, while the reverse was true for the porphyrins. Thus, the porphyrin ligand is not required for metal-ion catalysis of oxygenations of organic substrates by PhIO.
