General Description

1,2-bis(4-bromophenyl)disulfane 1,1,2,2-tetraoxide is a chemical compound that consists of two 4-bromophenyl groups linked by a disulfane bridge, with four oxygen atoms attached to the carbon atoms of the phenyl groups. 1,2-bis(4-bromophenyl)disulfane 1,1,2,2-tetraoxide is a dimer of the 1,2-bis(4-bromophenyl)disulfanyl radical, and it is known for its high reactivity and potential applications in organic synthesis and materials science. It can undergo redox reactions, exhibiting both oxidizing and reducing properties, and may be utilized as a reagent or intermediate in the synthesis of other organic compounds. However, its specific uses and potential hazards are yet to be fully characterized, and further research is needed to determine its practical applications and safety considerations.

A paradigm shift in rate determining step from single electron transfer between phenylsulfinylacetic acids and iron(III) polypyridyl complexes to nucleophilic attack of water to the produced sulfoxide radical cation: a non-linear Hammett

Mechanism of oxidative decarboxylation of phenylsulfinylacetic acids (PSAAs) by iron(III) polypyridyl complexes in aqueous acetonitrile medium has been investigated spectrophotometrically. An initial intermediate formation between PSAA and [Fe(NN)3]3+ is confirmed from the observed Michaelis–Menten kinetics and fractional order dependence on PSAA. Significant rate retardation with concentration of [Fe(NN)3]3+ is rationalized on the basis of coordination of a water molecule at the carbon atom adjacent to the ring nitrogen of the metal polypyridyl complexes by nucleophilic attack at higher concentrations. Electron-withdrawing and electron-releasing substituents in PSAA facilitate the reaction and Hammett correlation gives an upward ‘V’ shaped curve. The apparent upward curvature is rationalized based on the change in the rate determining step from electron transfer to nucleophilic attack, by changing the substituents from electron-releasing to electron-withdrawing groups. Electron-releasing substituents in PSAA accelerate the electron transfer from PSAA to the complex and also stabilize the intermediate through resonance interaction leading to negative reaction constants (ρ). Conversely, electron-withdrawing groups, while retarding the electron transfer exert an accelerating effect on the nucleophilic attack of H2O which leading to low magnitude of ρ+ compared to high ρ? values of electron-releasing groups. Marcus theory is applied, and a fair agreement is seen with the experimental values. Copyright
