Ra. Henderson et Ke. Oglieve, A NEW KINETIC PATTERN FOR THE SUBSTITUTION-REACTIONS OF INORGANIC COMPLEXES - STUDIES ON [FE2S2CL4](2-), Journal of the Chemical Society, Chemical Communications, (17), 1994, pp. 1961-1962
Kinetic studies on the substitution reactions of [Fe2S2Cl3(NCMe)](-) w
ith the nucleophiles L = Br- or RS(-) (R = Et or But) to form [Fe2S2Cl
3](2-) show that the rate of the reaction is inhibited by increasing t
he concentration of the nucleophile; this is a consequence of L bindin
g to the iron atom not undergoing substitution.
