Hydrolysis of (eta(5)-C5Me5)MMe4 (M = Mo, W) and the formation of organometallic oxides with mu(3)-CH methylidyne and mu-CH2 methylidene groups: Model compounds for catalysis on metal oxide surfaces

Abstract

The hydrolysis of (eta(5)-C5Me5)WMe4 leads to the formation of the two compounds (eta(5)-C5Me5)(2)W2O2(mu-CH2)(2) (6) and (eta(5)-C5Me5)(2)W2O2(mu-CH2)(mu-O) (9), containing both methylidene and oxo moieties in one molecule. Reaction of (eta(5)-C5Me5)MoMe4 with water leads to the trinuclear cluster (eta(5)-C5Me5)(3)Mo-3(mu-O)(2)(mu-CH2)(mu(3)-CH) (10) with oxo, methylidene, and methylidyne groups. Compounds 6, 9, and 10 were characterized by single-crystal X-ray structural analysis. 6, 9, and 10 can be considered as model compounds for catalysis on metal oxide surfaces.
