Nucleophilic Attack at CO Ligands

Binary metal carbonyls can also react with the hydroxyl groups of zeolites to form zeolite encaged anions, the reactivity being analogous to that of metal carbonyls with surface hydroxyl groups on metal oxide surfaces or with hydroxide ions in solution (Eq. 4.6). [98, 99] [Pg.329]

Here the braces denote surface groups and Z represents the zeolite. [Pg.329]

Iwamoto et al. [50] investigated the sorption of [Fe3(CO)x2] and [Fe2(CO)9] in hydrated NaY zeolite. They concluded from Infrared and ultraviolet-visible spectra that the sorption of [Fe2(CO)9] led to the formation of [HFe3(CO)n] , which interacts via the bridging carbonyl ligand with an OH group, as shown in Equation (4.1). [Pg.329]
