Abstract
The synthesis and characterization of two heterometallic clusters, [(IPr)Cu]2Fe(CO)4 (1) and [(IPr)ZnFe(CO)4]2 (2), derived from Collman's reagent are reported. Methylation of 1 with CH3I to produce (IPr)CuI and (IPr)CuFe(Me)(CO)4 (3) was used to calibrate the relative reactivity of 1 to the previously studied analogue (IPr)Cu-FeCp(CO)2. Bifunctional N2O activation by 1 resulted in oxidation of a CO ligand to carbonate rather than the more typically observed CO2, producing [(IPr)Cu]2(μ-CO3) (4) stoichiometrically along with an iron byproduct that was trapped with PPh3 as trans-Fe(CO)3(PPh3)2.
