The reactions of the complexes [MCl(η3-C3H4-R)(CO)2(phen)] (1a−c; M = Mo, W) with KCH2C(O)Ar afford the O-bound enolato complexes [M(η3-C3H4-R){OC(CH2)Ar}(CO)2(phen)] (2a−d). On the other hand, the reactions of molybdenum chloro complexes with KCH2CN yield the complexes [Mo(η3-C3H4-R)(CH2CN)(CO)2(phen)] (3a,b), in which the nitrile enolate ligand is C-bound. In addition to the spectroscopic characterization by means of IR and NMR, the structures of [Mo(η3-C3H5){OC(CH2)(naphthyl}(CO)2(phen)] (2c) and [Mo(η3-C3H4-Me-2)(CH2CN)(CO)2(phen)] (3a) were determined by X-ray diffraction.
