Ligand substitution solvent exchange reactions

The widespread use of fast-reaction methods has opened up the study of new types of reaction and new chemical species, and has raised new questions about physical aspects of mechanisms. Examples of types of reaction which could not be studied without fast-reaction techniques include the following among reactions of labile metal ions, ligand substitution, solvent exchange, and electron-transfer among organic reactions, many proton-transfer... 

An attempt is made to account quantitatively for the volumes of activation, AV, of ligand substitution processes. Causes of the pressure-dependence of AV include solvational change, for which a versatile analysis is developed. The pressure-independent AV values of solvent exchange reactions are good measures of the non-sol-vational components of AV for related net reactions. For water exchange, one can predict... 

Within solution inorganic chemistry, there would be no apparent reason to obtain NMR spectra at high pressures in structural characterization studies. It prevails that most applications of hp NMR spectroscopy relate to solvent exchange reactions on solvated metal ions their mechanisms often have direct bearing upon the kinetics and mechanisms of substitution of one or more solvent molecules from a metal center by other ligands. The first part of the results section provides ample illustration of the value of high-pressure measurements on transition metal and lanthanide ions, fully... 

As in the case of solvent exchange reactions, the rate and mechanism of ligand substitution reactions can be systematically tuned through manipulation of steric and electronic effects. The introduction of a metal-carbon bond on an inert metal...
