Studies of reactions between flavins and quinones, mercaptans, and enolates.
A. Equilibrium and second-order rate constants have been measured for the redox reaction between phthaloquinone and dihydroriboflavin (and its reverse) at a number of pH values. The equilibria and kinetic determinations are in agreement. No intermediates could be found in the reaction, and it is proposed that with this and other quinones electron transfer occurs within a complex of the flavin a...
متن کاملRATE CONSTANTS FUR THE ELECTRODE REACTIONS OF QUINONES IN CHLOROFORM: THE DEPENDENCE ON ELECTRODE MAmRIAL,S AND APPARENT STANDARD POENTIALS
The reduction process for some quinones has been studid by cyclic voltammeby, rotating disk electrode voltammetry and chronopotentiometry in chloroform at platinum, gold and glassy carbon electrodes using tetrabutylmonium perchlorate (TB AP) as supporting eiectrolyte. The results obtained from this study reveal that the reduction of the quinones is two one-electron processes, the first redu...

any physically reasonable set of transition-state and Eckart barrier parameters. Similarly, the fitted TST-Eckart curve was also found to be lower than the data points of Anastasis based on the rate of disappearance of methyl radicals, which, however, have been shown to be subject to substantial error due to the omission of other potential CH3 loss reactions.25 Our success in modeling the exper...
متن کاملElectrochemical oxidation of N-acyldopamines and regioselective reactions of their quinones with N-acetylcysteine and thiourea.
The metabolism of catechols often involves their oxidation to quinones and subsequent nucleophilic addition reactions with sulfur-containing compounds. Adducts formed during these reactions may play important roles in many biological systems. We have studied the electrochemical oxidation of N-acetyldopamine (NADA) and N-beta-alanyldopamine (NBAD) in the presence of two sulfur-centered nucleophi...
متن کاملFirst transamination reactions for the one-pot synthesis of substituted zwitterionic quinones.
A new and very efficient one-pot synthesis, in water, of 6 pi + 6 pi electron zwitterionic benzoquinonemonoimines involves the first examples of transamination reactions in quinonoid chemistry and allows the introduction of functionalities to, and the fine-tuning of the properties of, a large family of molecules with interesting potential, both in supramolecular chemistry and as multidentate li...
