Trifluoromethanesulfonato derivatives of ruthenium(II)

The reactivity of Ru(O2CNiPr2) 2(CO)2(PPh3)2 (1), towards CF 3SO3H (TfOH, trifloromethanesulfonic acid or triflic acid) has been studied and the products [Ru(O2CNiPr 2)(CO)2(PPh3)2][OTf] (2), and Ru(OTf)2(CO)2(PPh3)2 (3), have been obtained, the former being structurally characterised as one of the few examples of cationic N,N-dialkylcarbamato complexes. In compound 2, the N,N-di-iso-propylcarbamato group is bidentate. In experiments aimed at obtaining Ru(OTf)2(CO)2(PPh3)2 according to the literature method, i.e. from Ru(CO)3(PPh 3)2 and TfOH, the intermediate species [RuH(CO) 3(PPh3)2][OTf] (4), corresponding to the oxidative addition of triflic acid, has been intercepted. Treatment of this derivative in refluxing toluene followed by addition of methanol afforded the compound [RuH(CO)2(PPh3)2(CH 3OH)][OTf] (5), which has been characterised by single-crystal X-ray diffractometry.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C38H34Cl2O2P2Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 14564-35-3, in my other articles.

Ruthenium mediated C-H activation of 2-(arylazo)phenols: Characterization of an intermediate and the final organoruthenium complex

Reaction of 2-(arylazo)phenols with [Ru(PPh3) 2(CO)2Cl2] affords a family of organometallic complexes of ruthenium-(II) of type [Ru(PPh3)2(CO)(CNO-R)] , where the 2-(arylazo)phenolate ligand (CNO-R; R = OCH3, CH 3, H, Gl, and NO2) is coordinated to the metal center as tridentate C,N,O-donor. Another group of intermediate complexes of type [Ru(PPh3)2(CO)(NO-R)(H)] has also been isolated, where the 2-(arylazo)phenolate ligand (NO-R) is coordinated to the metal center as bidentate N,O-donor. Structures of the [Ru(PPh3)2(CO)(NO- OCH3)(H)] and [Ru(PPh3)2(CO)-(CNO-OCH 3)] complexes have been determined by X-ray crystallography. All the complexes are diamagnetic and show characteristic 1H NMR signals and intense MLCT transitions in the visible region. Both the [Ru(PPh 3)2(CO)-(NO-R)(H)] and [Ru(PPh3) 2(CO)(CNO-R)] complexes show two oxidative responses on the positive side of SCE.

RuCl2(PPh3)3 catalyzed liquid phase hydroformylation of propene under mild pressure conditions in alcoholic media: Isolation and characterization of species separated out during the reaction

Dichlorotris(triphenylphosphine)ruthenium(II), RuCl2(PPh3)3, catalyzed liquid phase hydroformylation of propene was carried out in ethanol. Mixture of two complexes, which get separated, were observed to form along with hydroformylation products under mild pressure of 9 bar at 175 C. These two complexes were identified as dicarbonylchlorohydridobis(triphenylphosphine)ruthenium(II), HRuCl(CO)2(PPh3)2 and dicarbonyldichlorobis(triphenylphosphine)ruthenium(II), RuCl2(CO)2(PPh3)2 which have been isolated and characterized. The crystal structure of one of the intermediates as determined by single crystal X-ray diffraction established this as cis form of RuCl2(CO)2(PPh3)2. The isolated complexes were found to be inactive towards hydroformylation of propene. A possible mechanism for the formation of these intermediate species and lower conversion for hydroformylation products is discussed.
