Equation for first order kinetics: The release behavior of first order equation expressed as log cumulative. The measured temperature dependent reaction rate constants are linearly related to the free energy change.
The sulfur-bridged dimeric dithiolato rhenium(V) chelate ( D), derived from 2-mercaptothiophenol, was monomerized to give ( M− L) in benzene upon reaction with various neutral and anionic monodentate ligands ( L) such as pyridine and its substituted derivatives, triarylphosphines, dimethyl sulfoxide, 4-picoline- N-oxide, and halide ions. The kinetic observations can readily be interpreted for all ligands by a unified mechanism in which the initial fast formation of a 1:1 ( DL) and 1:2 ( DL 2) adduct is followed by the slow monomerization of each species so formed.
The use of different ligands gave insight into different steps of the same multistep mechanism. The kinetics of ligand exchange between free L and the monomeric complexes was also studied; an associative pathway has been proposed to interpret the results. The crystal structures of two new monomeric ML complexes (with L = 4-acetylpyridine and 1,3-diethylthiourea) are reported.
