Abstract

Kinetics and equilibrium measurements for the reversible binding of CN- to carbonylated phthalocyaninatoiron(II) ([Fe(pc)(CO)-(dmso)]) have been carried out, at 25.0°C in dimethyl sulfoxide. The rate of cyanide binding to [Fe(pc)(CO)(dmso)] is limited by the rate of CO dissociation and the ultimate formation of [Fe(pc)(CN)2]2- does not occur via [Fe(pc)(CO)(CN)]-. These results agree with a strong delabilization effect by CO on trans dmso. Implications of this effect are discussed.
