The iodide catalysis effect

An aspect of the metal s coordination environment and nucleophilicity is the influence that iodide ion can have on the reactions of certain transition metal nucleophiles with Mel. This is an aspect of particular relevance to the homogeneously catalysed carboxylation of methanol to acetic acid which employs a rhodium iodide-promoted catalyst (Forster, 1979 and references therein). 

Kinetic studies on the iodide-catalysed reaction (32) demonstrate that in methanol an equilibrium between [Ir(cod)(phen)] and iodide (which can be studied spectrophotometrically) is established rapidly, and that both species
