1,1?-Bis(diphenylphosphino)ferrocene (dppf) reacted with RuCl(Ph3P)2Cp* to give RuCl(dppf)Cp* in good yield. The complex reacted with AgBF4 in acetonitrile to give [Ru(CH3CN) (dppf)Cp*]BF4 quantitatively and in acetone to give [Ru(eta2-O2) (dppf)Cp*]BF4 in good yield. The structure of the latter was determined by X-ray analysis. (±)-BINAP and (±)-DIOP were reacted with [RuCl2Cp*]n/Zn to give RuCl[(±)-BINAP]Cp* and RuCl[(±)-DIOP]Cp*, respectively, in moderate yields. They reacted with phenylacetylene in the presence of NH4PF6 to afford the corresponding RuII phenylacetylide complexes. The asymmetric condensation of phenylacetylene with allyl alcohol in the presence of these diphosphine complexes was unsuccessful.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru.

The molecular building blocks Fe(II)Pc (Pc = phthalocyaninato2-), Fe(III)Pc, ZnPc, Cp(dppe)Fe, and Cp(PPh3)2Ru were combined in the cyanide-bridged dinuclear reference compounds with M-CN-ZnPc and M-CN-FePc-CN arrays containing Fe(II)Pc and Fe(III)Pc. The linear trinuclear species with the M(mu-CN)Fe(mu-CN)M’ backbone were prepared for both Fe(II)Pc and Fe(III)Pc centers, for terminal Fe/Fe, Fe/Ru, and Ru/Ru combinations and for all three possible cyanide orientations (M-CN-Fe-NC-M’, M-CN-Fe-CN-M’, and M-NC-Fe-CN-M’). The 15 complexes obtained were identified from their IR spectra and six structure determinations. The preferred orientation of the cyanide bridges could be established starting from the [Fe-NC-Fe(III)Pc-CN-Fe]+ complex, which is labile in solution and isomerizes to the corresponding [Fe-CN-Fe(III)Pc-NC-Fe]+ complex. A kinetic analysis of this isomerization has yielded an activation barrier of roughly 110 kJ/mol.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), you can also check out more blogs about32993-05-8

The Cp(PPh3)2Ru-nCR=CH2 complexes 2 – 4 (n = 0, 2, R = H; n = 3, R = CH3) are prepared by treatment of the chloride 1 with the appropriate organomagnesium halides.The vinyl complex 2 eliminates a PPh3 ligand above 100 deg C and reacts with ethylene (20 – 30 bar) by insertion into the Ru – vinyl bond to give the (eta3-1-methylallyl)ruthenium complex 6a.The 3- and 4-alkenyl compounds 3 and 4 isomerize at 80 – 100 deg C after dissociation of one PPh3 via an (eta2-alkadiene)hydridoruthenium intermediate, e.g. 7, to form the eta3-allyl complexes 6, 8, and 9, respectively.The stable (eta1,eta2-4-alkenyl)ruthenium compounds 10 – 12 are formed if isomerization by beta-H-elimination is prevented by E-configuration of Ru and beta-H in a conformatively inflexible cyclopropyl system.The 31P chemical shifts of 2 – 4 and the (eta1-allyl)ruthenium complexes, of 10 – 12, and of the eta3-allyl complexes 6a, 8, 9, 13a are characteristic for the corresponding type of compounds.

An unprecedented ruthenium-catalyzed direct and selective alkyne hydrochlorination is reported and leads to vinylchlorides in excellent yields with atom economy. The reaction proceeds at room temperature from terminal alkynes and provides a variety of chloroalkenes. Only the regioisomer resulting from the formal Markovnikov addition is selectively formed. Mechanistic studies show the stereoselective syn addition of HCl to alkynes at room temperature and suggest a chloro hydrido RuIV species as a key intermediate of the reaction.

Two new ruthenium complexes, [Ru(eta5-Cp)(PPh3)(2,2?-bipy-4,4?-R)]+ with R = -CH2OH (Ru1) or dibiotin ester (Ru2) were synthesized and fully characterized. Both compounds were tested against two types of breast cancer cells (MCF7 and MDA-MB-231), showing better cytotoxicity than cisplatin in the same experimental conditions. Since multidrug resistance (MDR) is one of the main problems in cancer chemotherapy, we have assessed the potential of these compounds to overcome resistance to treatments. Ru2 showed exceptional selectivity as P-gp inhibitor, while Ru1 is possibly a substrate. In vivo studies in zebrafish showed that Ru2 is well tolerated up to 1.17 mg/L, presenting a LC50 of 5.73 mg/L at 5 days post fertilization.
