Abstract

The kinetics and mechanisms of the isomerization reactions of three (dialkylthiolato)hexacarbonyldiiron complexes (m-PhCH2S)(m-RS)Fe2(CO)6, (R = Me, Et, Me3C) have been studied by means of 1H NMR. The related kinetic parameters have been obtained and the probable mechanism of the reactions has been proposed. The isomerization reactions proceed most probably via a transition state involving the bond relaxation of one S-Fe bond and the rotation of another S-Fe bond.

Key words: REACTION KINETICS, NMR SPECTROMETRY, IRON COMPLEX, CARBONYL COMPLEX, PROTON MAGNETIC RESONANCE SPECTROMETRY, ISOMERIZATION REACTION, SULFIDE COMPLEX, BRIDGE COMPOUNDS
