Kinetics and mechanism of oxidation of paracetamol by an Anderson-type 6-molybdocobaltate(III) in acidic medium

Recent Advances of Anderson-Type Polyoxometalates as Catalysts Largely for Oxidative Transformations of Organic Molecules

“…So, Anderson-type POMs still have great potential as a heterogeneous catalyst in organic reactions. In the same year, Sawant and co-worker investigated the application of Co-based Anderson-type POMs, Co III (OH)6Mo6O18] 3− , in catalyzed oxidation of acetaminophen in the aqueous media when the pH values are 1 or 2 [41]. In this reaction, the electron transfer from neutral acetaminophen to anion, and then in the step of rate determination, the free radicals are further oxidized to N-acetylquinone imide as an intermediate, and what is In the same year, Sawant and co-worker investigated the application of Co-based Anderson-type POMs, Co III (OH) 6 Mo 6 O 18 ] 3− , in catalyzed oxidation of acetaminophen in the aqueous media when the pH values are 1 or 2 [41].…”

“…Reducing or avoiding producing harmful products is the question of organic synthesis reaction and the focus of "green" chemical research [31][32][33][34]. With the development of Anderson-type POMs in the catalytic reaction, the researchers found that the replacement of a traditional metal or non-metal catalyst is feasible with Anderson-type POMs or their derivatives [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. This system not only can improve the catalytic efficiency, but also generate less by-product in the process.…”

Ruthenium(III) catalyzed oxidation of paracetamol by chloramine‐T in aqueous alkaline medium – A kinetic and mechanistic pathway

“…The estimation of paracetamol by titrimetric and spectrophotometric has been performed in studies. [18][19][20][21][22] As the oxidation studies are scanty, it is for this reason that we were prompted to undertake the kinetics of oxidation of the paracetamol (heretofore written as PCM) with chloramine-T to know more about its pattern of reactivity and to perceive the logical conditions in such a manner that paracetamol can be determined quantitatively in solutions by this oxidant in aqueous alkaline medium from the following viewpoints: First, the analytical facts regarding the speciation of chloramine-T species in an alkaline medium can be achieved. Second, the pattern of reactivity of ruthenium(III) as a catalyst can also be understood for a proper proposition of the reaction mechanism.…”

“…Due to its clinical effects as an inhibitor are still indefinite, new findings are needed in the mode of action of paracetamol which is an advancement in physiological and pharmacological points of view. The estimation of paracetamol by titrimetric and spectrophotometric has been performed in studies 18–22 . As the oxidation studies are scanty, it is for this reason that we were prompted to undertake the kinetics of oxidation of the paracetamol (heretofore written as PCM) with chloramine‐T to know more about its pattern of reactivity and to perceive the logical conditions in such a manner that paracetamol can be determined quantitatively in solutions by this oxidant in aqueous alkaline medium from the following viewpoints: First, the analytical facts regarding the speciation of chloramine‐T species in an alkaline medium can be achieved.…”
