TL;DR: In this paper, the rate constants for reactions involving Fe(phen)32+(phen = 1,10-phenanthroline), Fe(5-NO2phen) 32+, (iii) 2,4-dinitrochlorobenzene, and (iv) crystal violet with either hydroxide or cyanide ions are increased markedly when two water/organic microemulsions formed from liquid components are used as reaction media; a similar though less significant change is observed in the related rates of aquation (hydrolysis).
Abstract: Relative to the rate constants for reactions in aqueous solutions the rate constants for reactions involving (i) Fe(phen)32+(phen = 1,10-phenanthroline), (ii) Fe(5-NO2phen)32+, (iii) 2,4-dinitrochlorobenzene, and (iv) crystal violet with either hydroxide or cyanide ions are increased markedly when two water/organic microemulsions formed from liquid components are used as reaction media; a similar though less significant change is observed in the related rates of aquation (hydrolysis).

TL;DR: The (4-NO2ImH)+ salt of the [RuCl4(5-NO 2Im)2]− anion was obtained by reacting 4-nitroimidazole (4NO2IM) with activated RuCl3 in aqueous HCl solution as discussed by the authors.

TL;DR: In this article, the rate law of the O-to-N-linkage isomerization reaction was investigated in the presence of the base-catalyzed O-bonded N-isomerization.

TL;DR: It is found that the solvation effect is indispensable to promote the dissociation of the chloride anion from the complex.
Abstract: The ligand exchange process of cis-platin in aqueous solution was studied using RISM–SCF–SEDD (reference interaction site model–self-consistent field with spatial electron density distribution) method, a hybrid approach of quantum chemistry and statistical mechanics. The analytical nature of RISM theory enables us to compute accurate reaction free energy in aqueous solution based on CCSD(T), together with the microscopic solvation structure around the complex. We found that the solvation effect is indispensable to promote the dissociation of the chloride anion from the complex.

TL;DR: In this paper, the Grunwald-Winstein treatment of solvolyses in mixed solvents is discussed in terms of the Grinwald-Wiener treatment of similar complexes, including methanol-, ethanol-, dioxan-, acetone-, acetic acid-, and t-butyl alcohol-water mixtures.
Abstract: Rates are reported for spontaneous aquation of [Co(NH3)5Cl]2+, and trans-[Co(en)2Cl2]+, and of mercury(II)-assisted aquation of [Co(NH3)5Cl]2+ and [Rh(NH3)5Cl]2+, in a range of binary mixed solvents, including methanol-, ethanol-, dioxan-, acetone-, acetic acid-, and t-butyl alcohol-water mixtures. These results, and previously published results on similar complexes, are discussed in terms of the Grunwald–Winstein treatment of solvolyses in mixed solvents.
