Phosphine complexes of ruthenium

Figure 1.22 Syntheses of tertiary phosphine complexes of ruthenium.

The water soluble tertiary phosphine complex of ruthenium(II), [RuCl2(PTA)4], (PTA=l,3,5-triaza-7-phosphaadamantane) was used as catalyst precursor for the hydrogenation of CO2 and bicarbonate in aqueous solution [51]. For this relatively...

The highly developed enantioselective hydrogenation of prochiral functionalized alkenes using chiral phosphine complexes of ruthenium or rhodium as catalysts has become very common in academic laboratories as well as in industry... 

Unlike the above example, the majority of five-coordinate complexes appear to undergo oxidative-addition reactions in two separate steps. Additions to the bis phosphine complexes of ruthenium(O) (36) and osmium(O) (39) (XIV) are the most thoroughly studied examples of this generalization (see Section IV). The configurations of these complexes have been established by infrared spectroscopy and, in the case of the osmium complex, by X-ray diffraction (72), Addition of an electrophile A" " (for example H+, HgX+, or Br+ from Br2) to the five-coordinate complexes...

The influence of steric factors on reactivity and on selectivity has been discussed for the catalysis, by a variety of phosphine complexes of ruthenium, iridium, and platinum, of the isomerization of 4-vinylcyclo-hexane. Titanium tetra-( - )-menthoxide plus tri-isobutylaluminium catalyse stereoselective isomerization of racemic alk-l-enes. ...
