Abstract
New MoVI-dioxodialkyl complexes, MoO2R2(bipy), R = CH2CH2Ph and p-MeC6H4CH2; bipy = 2,2'-bipyridine, have been synthesized. The i.r. and the 1H-n.m.r. spectra of these complexes are noted. The structure of MoO2(o-MeC6H4CH2)2(bipy) was determined by X-ray analysis. Significant differences in the redox characteristics of these dioxodialkylcompounds are reflected in the contrasting patterns: whereas reduction of MoO2-(CH2CH2Ph) 2(bipy) is a reversible one-electron process, under similar conditions MoO2(p-MeC6H4CH2)2(bipy) and MoO2(o-MeC6H4CH2)2(bipy) are reduced irreversibly. Similarly, solutions of MoO2(CH2CH2Ph)2(bipy) remain unchanged but oxygenated organic products are formed from MoO2(p-MeC6H4CH2)2(bipy) and MoO2 (o-MeC6H4CH2)2(bipy).
