Abstract
New MoVI -dioxodialkyl complexes, MoO2 R2 (bipy), R = CH2 CH2 Ph and p-MeC6 H4 CH2 ; bipy = 2,2'-bipyridine, have been synthesized. The i.r. and the 1 H-n.m.r. spectra of these complexes are noted. The structure of MoO2 (o-MeC6 H4 CH2 )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 -(CH2 CH2 Ph) 2 (bipy) is a reversible one-electron process, under similar conditions MoO2 (p-MeC6 H4 CH2 )2 (bipy) and MoO2 (o-MeC6 H4 CH2 )2 (bipy) are reduced irreversibly. Similarly, solutions of MoO2 (CH2 CH2 Ph)2 (bipy) remain unchanged but oxygenated organic products are formed from MoO2 (p-MeC6 H4 CH2 )2 (bipy) and MoO2 (o-MeC6 H4 CH2 )2 (bipy).
