Dioxobis

In /r-bridged dimers, two phthalocyanine moieties are linked by one or more bridging atoms such as oxygen or halogens. Niobium(V) oxide tribromide (NbOBr,) when treated with phthalonitrile in 1-chloronaphthalene at 230CC for 3 hours produces /r-bromo-/t-dioxobis[nio-bium(V) phthalocyanine] tribromide in 52%.232...

With the same synthetic sequence, labeled ribose molecules produced AIRs labeled on the ribose moiety. From D-erythrose and (l3C)NaCN, the Fischer-Kiliani synthesis, as modernized by Serianni et al.59 produced D-(l-l3C)ribose and D-(l-l3C)arabinose. The labeled arabinose was transformed into D-(2-l3C)ri-bose in the presence of dioxobis(2,4-pentanedionato)-0-0 -molybdenum(VI) in... [Pg.295]

The crystal structure of dioxobis-(l,3-diphenylpropanedionato)molybdenum(vi) has been determined by X-ray crystallography. The two cis-dioxo-groups involve Mo—O bond lengths of 169.6 pm, and the length of the Mo—O bonds in the chelate rings average 216.7 pm trans to the oxo-atoms, and 199.3 pm cis to these atoms.534...

Similarly, dioxobis(triphenylphosphane)platinum reacts with HFA. Ring contraction has been achieved with triphenylphosphane. An unstable bis adduct which is believed to be a seven-membered ring has also been reported (137). [Pg.288]

These complexes have been used as starting materials in the preparation of other alkoxy and phenoxy complexes, phenylimido complexes, analogous amine complexes, dioxotetrapyridinerhenium(V) salts and dioxobis(ethylene-diamine) rhenium (V) salts, cyano complexes of rhenium-(V), acetylacetone complexes, hydrides, carbonyls, and isonitrile complexes. The products of reactions using the materials described here as sources are normally easier to purify than those obtained by other methods. [Pg.148]

Dioxobis(2,4-pentanedionato-0,0 )molybdenum(VI) has been reported as a catalyst for molybdate-catalyzed epimerizations in polar aprotic solvents such as dimethylformamide (DMF) [30]. In spite of more interesting reaction equilibria, the method is not as convenient or as economical as the classical aqueous one due to necessary additional purification procedures. [Pg.19]
