A comparison of Cp*- and Tp-ruthenium carbyne complexes prepared via site selective electrophilic addition to neutral ruthenium vinylidenes
The synthesis and characterization of a series of ruthenium carbyne complexes supported by either pentamethylcyclopentadienyl (Cp*) or hydridotris(pyrazolyl)borate (Tp) ligands are discussed. Reacting the neutral ruthenium(II) vinylidenes [Cp*Cl(PPh3)Ru(CCHR)] (1) or [TpCl(PPh3)Ru(CCHR)] (2) with excess HBF4 ? Et 2O yields the ruthenium(IV) carbynes [Cp*Cl(PPh 3)Ru(CCH2R)][BF4] (3: R = tBu, 3a; R = nBu, 3b; R = Ph, 3c), and [TpCl(PPh3)Ru(CCH 2R)][BF4] (4: R = tBu, 4a; R = nBu, 4b; R = Ph, 4c). Complexes 3a and 3b are isolable solids, whereas 3c and 4a-c must be prepared and examined in solution at low temperatures using variable temperature NMR spectroscopy. In contrast, reactions of 1 or 2 (R = Ph) with MeOTf selectively yield the chloride abstracted products [Cp*(OTf) (PPh3)Ru(CCHPh)] (5) or [Tp(OTf)(PPh3)Ru(CCHPh)] (6), respectively, along with one equivalent of MeCl. When R = tBu or nBu, the reactions are much less selective. The relative stabilities of the complexes reported are compared and discussed.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 92361-49-4 is helpful to your research., Synthetic Route of 92361-49-4
