Meso Tetraphenylporphyriniron Iii Chloride Catalyzed Oxidation Of Aniline And Its Substituents

Abstract

Chemists have shown a great deal of attention towards modeling newlineof cytochrome P450 monooxygenase using synthetic metalloporphyrins as newlinethey have a strapping resemblance to heme in both structures and catalytic newlineproperty The potential of the heme group is to combine with tiny ligands newlineincluding molecular oxygen in enzymatic oxidations The contribution of newlineheme in these oxidation processes aggravated chemists to turnover from these newlinenaturally occurring catalysts and operate them into industrial processes In newlineorder to learn the core of the heme group the porphyrin ring with the central newlinemetal iron atom has been selected Metalloporphyrin iron complexes are the newlinesubject in a number of findings as they can be added as catalysts in selective newlineoxidation of aniline Many mechanistic studies have revealed that halogenated newlinemetalloporphyrin complexes are excellent catalysts for difficult oxidations newlinewith high selectivity The iron complexes with mesotetraphenyl groups are newlineexpansively considered as models of the natural ironporphyrins due to their newlineconstructive properties such as catalytic and semiconducting properties Iron newlinecomplexes of tetraphenylporphyrins which can be regarded as macrocyclic newlineligands has an intermediate structure sandwiched between common natural newlineiron porphyrins with cytochrome P450 To complement the studies in the field newlineof the catalytic oxidation of aniline the oxidation of aniline by newlinevarious oxidants catalysed by first generation catalyst mesoiv newlinetetraphenylporphyrinironIII chloride 5101520tetraphenyl21h23hporphineiron newlineIII chloride was taken for the study newlineThe present work was undertaken with the objective of configuring newlinethe mechanistic studies on mesotetraphenylporphyrinironIII chloride newlinecatalyzed oxidation of anilines by oxidants namely potassium newlineperoxymonosulphate oxone metachloroperbenzoic acid magnesium newlinemonoperoxypthalate sodium perborate and tertiary butyl hydroperoxide in newlineaqueous acetic acid medium The order of the reactions was found to be two newlinein all the above mentioned oxidants with respect to aniline newline
