Kinetic parameters are reported for hexachloroiridate (IV) oxidation of t-butyl-catechol (4-t-butyl-benzene-1,2-diol), hydroquinone (benzene-1,4-diol) and its 2-t-butyl derivative in binary aqueous mixtures containing methanol, ethanol, t-butyl alcohol, acetone, dimethyl sulfoxide, or dimethylformamide. Solubilities are reported, and transfer chemical potentials thence derived, for hydroquinone in a range of such media and for catechol, 2,4-bis-(t-butyl)catechol, methylhydroquinone and t-butyl- hydroquinone in methanol-water mixtures. On the basis of a selection of these kinetic and thermodynamic rnyesults we have analysed reactivity trends for several of these hexachloroiridate(IV) oxidations into initial state and transition state contributions

Abstract
Kinetic parameters are reported for hexachloroiridate (IV) oxidation of t-butyl-catechol (4-t-butyl-benzene-1,2-diol), hydroquinone (benzene-1,4-diol) and its 2-t-butyl derivative in binary aqueous mixtures containing methanol, ethanol, t-butyl alcohol, acetone, dimethyl sulfoxide, or dimethylformamide. Solubilities are reported, and transfer chemical potentials thence derived, for hydroquinone in a range of such media and for catechol, 2,4-bis-(t-butyl)catechol, methylhydroquinone and t-butyl- hydroquinone in methanol-water mixtures. On the basis of a selection of these kinetic and thermodynamic rnyesults we have analysed reactivity trends for several of these hexachloroiridate(IV) oxidations into initial state and transition state contributionsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
