摘要：

Substitution of the first chloro-ligand in [Fe4S4Cl4](2-) by 4-RC6H4S- (R = CF3, Cl, H, Me or MeO), in the presence of [H2N(CH2)(3)CH2](+), involves initial binding of thiolate, followed by protonation and finally chloride dissociation; the rate of protonation is facilitated by electron-withdrawing R-substituents indicating that Fe-thiolate bond length changes modulate proton transfer.
