The kinetics of the oxidative degradation of an azo dye Metanil Yellow (MY) was investigated in aqueous solution using dirhodium(II) caprolactamate, Rh2(cap)4, as a catalyst in the presence of H2O2 as oxidizing agent. The reaction process was followed by UV/Vis spectrophotometer. The decolorization and degradation kinetics were investigated and both followed a pseudo-first-order kinetic with respect to the [MY]. The effects of various parameters such as H2O2 and dye concentrations, the amount of catalyst and temperature have been studied. The studies show that Rh2(cap)4 is a very effective catalyst for the formation of hydroxyl radicals HO* which oxidized and degraded about 92% of MY into CO2 and H2O after 24 h as measured by total carbon analyzer.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Dirhodium(II) tetrakis(caprolactam)( cas:138984-26-6 ) is researched.Application of 138984-26-6.McLaughlin, Emily C.; Choi, Hojae; Wang, Kan; Chiou, Grace; Doyle, Michael P. published the article 《Allylic Oxidations Catalyzed by Dirhodium Caprolactamate via Aqueous tert-Butyl Hydroperoxide: The Role of the tert-Butylperoxy Radical》 about this compound( cas:138984-26-6 ) in Journal of Organic Chemistry. Keywords: allylic oxidation dirhodium caprolactamate catalyst. Let’s learn more about this compound (cas:138984-26-6).

Dirhodium(II) caprolactamate exhibits optimal efficiency for the production of the tert-butylperoxy radical, which is a selective reagent for hydrogen atom abstraction. These oxidation reactions occur with aqueous tert-Bu hydroperoxide (TBHP) without rapid hydrolysis of the caprolactamate ligands on dirhodium. Allylic oxidations of enones yield the corresponding enedione in moderate to high yields, and applications include allylic oxidations of steroidal enones. Although methylene oxidation to a ketone is more effective, Me oxidation to a carboxylic acid can also be achieved. The superior efficiency of dirhodium(II) caprolactamate as a catalyst for allylic oxidations by TBHP (mol % of catalyst, % conversion) is described in comparative studies with other metal catalysts that are also reported to be effective for allylic oxidations That different catalysts produce essentially the same mixture of products with the same relative yields suggests that the catalyst is not involved in product-forming steps. Mechanistic implications arising from studies of allylic oxidation with enones provide new insights into factors that control product formation. A previously undisclosed disproportionation pathway, catalyzed by the tert-butoxy radical, of mixed peroxides for the formation of ketone products via allylic oxidation has been uncovered.

Oxidative cleavage reactions of arylalkenes by tert-Bu hydroperoxide that occur by free radical processes provide access to carboxylic acid or ketone products. However, the pathway to these cleavage products is complex, initiated by regioselective oxygen radical addition to the carbon-carbon double bond. Subsequent reactions of the initially formed benzyl radical lead eventually to carbon-carbon cleavage. Thorough investigations of these reactions have identified numerous reaction intermediates that are on the pathways to final product formation, and they have identified a new synthetic methodol. for the synthesis of peroxy radical addition-induced hydroperoxide formation.

When you point to this article, it is believed that you are also very interested in this compound(138984-26-6)Formula: C24H40N4O4Rh2 and due to space limitations, I can only present the most important information.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Stereoselective Synthesis of Chiral Sulfilimines from N-Mesyloxycarbamates: Metal-Nitrenes versus Metal-Nitrenoids Species, published in 2015-04-03, which mentions a compound: 138984-26-6, mainly applied to mesyloxycarbamate metal nitrene nitrenoid crystallog; stereoselective preparation chiral sulfilimine, Formula: C24H40N4O4Rh2.

The synthesis of a variety of chiral sulfilimines and sulfoximines is described. The amination of thioethers with a chiral N-mesyloxycarbamate was achieved in high yields and stereoselectivities using Rh2[(S)-nttl]4 as catalyst in the presence of 4-dimethylaminopyridine (DMAP) and a pyridinium salt, such as bis(DMAP)CH2Cl2 or a viologen salt. These additives proved instrumental to enhance both the yield and the stereochem. discrimination of the reaction. Mechanistic studies and control experiments have elucidated the role of these additives. DMAP served as an apical ligand for the rhodium catalyst: an x-ray crystal structure of the (DMAP)2·[Rh2{(S)-nttl}4] complex was obtained. This complex displayed a lower and irreversible redox potential. Control experiments with preformed Rh(II)-Rh(III) complex suggested such a catalytically active species in the thioether amination process. Diastereoselectivities were influenced by the sulfonyloxy leaving group, ruling out the possibility of a common metal nitrene species and instead suggesting a rhodium-nitrenoid complex. It is believed that the bispyridinium salt played the role of a phase transfer catalyst, influencing both the yield and the diastereoselectivity of the reaction.

Formula: C24H40N4O4Rh2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Dirhodium(II) tetrakis(caprolactam), is researched, Molecular C24H40N4O4Rh2, CAS is 138984-26-6, about Highly selective enantiomer differentiation in intramolecular cyclopropanation reactions of racemic secondary allylic diazoacetates.. Author is Doyle, Michael P.; Dyatkin, Alexey B.; Kalinin, Alexey V.; Ruppar, Daniel A.; Martin, Stephen F.; Spaller, Mark R.; Liras, Spiros.

Highly efficient enantiomer differentiation of racemic secondary allylic diazoacetates in intramol. cyclopropanation reactions has been achieved using chiral dirhodium(II) carboxamidates. Dirhodium(II) tetrakis[methyl 2-oxazolidinone-4(S or R)-carboxylate], Rh2(4S-MEOX)4 or Rh2(4R-MEOX)4, provides the highest levels of enantiomer selectivity in cyclizations of racemic 2-cycloalken-1-yl diazoacetates affording enantiomeric excesses of 94-95% (C5 and C6) or 83% (C7). In reactions catalyzed by Rh2(4S-MEOX)4, (1S)-cycloalk-2-en-1-yl diazoacetates undergo cyclopropanation, whereas (1R)-cycloalk-2-en-1-yl diazoacetates form 2-cycloalkenones and 1-methylene-2-cycloalkenes. The mirror image isomers are formed from reactions catalyzed by Rh2(4R-MEOX)4. Thus, refluxing 2-cyclohexen-1-yl diazoacetate (I) with Rh2(4S-MEOX)4 in CH2Cl2 gave a 40% yield of bicyclic lactone (II) in 94% enantiomeric excess.
