Transition metal carbonyl cluster chemistry: some new aspects of carbon monoxide catalysis

Some aspects of the chemistry of transition metal carbonyl clusters are reviewed in the following areas: (i) aspects of molecular chemistry of metal clusters and of particular C1 species, bonded to the metal frame of the clusters, which can be models for a mechanistic approach to catalytic CO reduction; (ii) homogeneous catalysis of syn-gas with metal clusters, with particular reference to C1 chemistry; (iii) heterogeneous catalysis in the same area with metal clusters supported on inorganic oxides.
