The five-fold coordinated ruthenium (II) catalyst RuCl2(PPh3)(3) is heterogenized on the surface of amine functionalized mesoporous silica material SBA-3 and studied by BET, XRD and P-31 CP-MAS solid-state NMR. The spectra indicate the replacement of one or two of the triphenyl-phosphine...
1H-NMR analysis revealed that the ruthenium complex reacted with the alcohol, generating in situ a ruthenium alkoxide. This species became a more active initiator of ring-opening polymerization than was RuCl2(PPh3)3. The obtained polylactones were characterized by 1H- and 13C-NMR and matrix-...
A new ruthenium complex—[RuCl 2 (PPh 3 ) 2 (3,5-Me 2 HPz) 2 ] has been obtained and characterized by IR, 1 H NMR and UV-VIS measurements. Crystal and molecular structure of the complex has been determined. The electronic structure of the complex has been calculated by TDDFT ...

The widespread soluble complex RuCl2(PPh3)3 is evidently not the true catalyst in numerous hydrogen transfer reactions where it has been utilized. In the presence of alcohol donors, particularly under boiling conditions, the complex is swiftly reduced to Ru(0) and forms nanosized clusters which ...
† From this solution, reddish-brown microcrystals of binuclear ruthenium species [(PPh3)2ClRu- (m-Cl)3Ru(PPh3)2(h1-P4)] 2 are obtained after layering with n-hexane.Release of two equivalents of PPh3 into the solution (31P NMR detected) accompanies the formation of the binuclear complex...
