The last decade has witnessed tremendous advances in the design of anticancer gold complexes containing tertiary phosphines, a class of ligands that have significantly contributed to the development of metal complexes owing to their stabilizing effect. The promising in vitro antiproliferative properties of the phosphine-containing organogold compound auranofin [1-(thio-kS)-2,3,4,6-tetra-O-acetyl-beta-D-glucopyranose](triethylphosphine-kP)gold(I), originally used to treat rheumatoid arthritis, inspired the extensive application of monodentate phosphines in the development of anticancer gold complexes. Meanwhile, the use of diphosphine ligands promoted advances in the preparation of chelated gold complexes as well as mixed-metal and mixed-ligand complexes that have superior anticancer activity. The present report summarizes the current state of knowledge of diphosphine ligands in the development of anticancer gold complexes, and explores challenges and opportunities in designing gold-containing mixed-metal and mixed-ligand complexes that have anticancer action.

A diphosphination of arynes with diphosphines has been developed. The reaction of stable aryne precursors, 2-(trimethylsilyl)aryl triflates, with tetraaryldiphosphines proceeds in the presence of fluorine- or carbonate-based activators to deliver the corresponding diphosphinated products, sterically and electronically tuned 1,2-bis(diphenylphosphino)benzene (dppbz) derivatives, which can find wide application in transition metal catalysis and material science. Additionally, preliminary computational studies on the reaction mechanism are also reported.

Cobalt complexes bearing enantiopure, bidentate bis(phosphine) ligands exhibit extraordinary activity and stereoselectivity for the hydrogenation of enamides. Optimal performance was observed in polar protic solvents such as methanol, an industrially preferred green solvent but a medium that is often a poison for reduced Earth abundant metals. The interaction of the low-spin cobalt(II) dialkyl complex, (R,R)-(iPr-DuPhos)Co(CH2SiMe3)2, with alcohols including 4-methoxyphenol, pinacol, and CH3OH was studied. With the alcohols lacking beta-hydrogens, cobalt bis(alkoxide) complexes were isolated and structurally characterized. With methanol, protonolysis of the alkyl ligands was again observed followed by dehydrogenation of the alcohol and [(R,R)-(iPr-DuPhos)Co]2(mu-CO)2 was isolated. Both solid-state and solution EXAFS studies were conducted to establish the spectroscopic signatures of bis(phosphine) cobalt(II) and cobalt(0) complexes relevant to catalytic hydrogenation and also to probe the role of phosphine dissociation in methanol.

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.Application In Synthesis of 1,2-Bis(diphenylphosphino)benzene, you can also check out more blogs about13991-08-7

We describe the development of (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2, a versatile precatalyst scaffold for Pd-catalyzed cross-coupling. Our new system is more active than commercially available (eta3-cinnamyl)2(mu-Cl)2Pd2 and is compatible with a range of NHC and phosphine ligands. Precatalysts of the type (eta3-1-tBu-indenyl)Pd(Cl)(L) can either be isolated through the reaction of (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2 with the appropriate ligand or generated in situ, which offers advantages for ligand screening. We show that the (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2 scaffold generates highly active systems for a number of challenging cross-coupling reactions. The reason for the improved catalytic activity of systems generated from the (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2 scaffold compared to (eta3-cinnamyl)2(mu-Cl)2Pd2 is that inactive PdI dimers are not formed during catalysis.

The bimetallic complexes CpRu(P-P)X [Cp = n5-C5H 5; X = Cl, H; P-P = dppf (1,1?-bis(diphenylphosphino)ferrocene) , dppr (1,1?-bis(diphenylphosphino)ruthenocene), dppo (1,1?- bis(diphenylphosphino)-osmocene), dippf (1,1?-bis(diisopropylphosphino) ferrocene), dcpf (1,1?-bis(dicyclohexylphosphino)ferrocene)], Cp*Ru(P-P)X [Cp* = n5-C5Me5; X = Cl, H; P-P = dppf, dippf, dppomf (1,1?-bis(diphenylphosphino) octamethylferrocene), dppc (1,1?-bis(diphenylphosphino)cobaltocene)], [Cp*Ru(P-P)X]+ (X = H, CCPh; P-P = dppc+), and [Cp*Ru(P-P)L]2+ (L = CH3CN, t-BuCN; P-P = dppc -) have been synthesized. Most of the chloride and hydride complexes have been studied by cyclic voltammetry. The X-ray structures of [Cp*Ru(dppc)CH3CN][PF6]2 and [Cp*Ru(dppc)CCPh] [PF6] have been determined. Protonation of [Cp*Ru(dppc)CCPh] + gives the vinylidene complex [Cp*Ru(dppc)CCHPh]2+. The Co(III/II) potential of the dppc+ ligand undergoes a cathodic shift upon coordination in [Cp*Ru-(dppc)H]+ and an anodic shift upon coordination in [Cp*Ru(dppc)CH3CN] . The 1H NMR spectrum of Cp*Ru(dppc)H is consistent with its formulation as a Co(II)/Ru(II) complex. As gauged by their reactivity toward iminium cations, the hydride complexes are poor hydride donors; proton and electron transfer are dominant. CpRu(dippf)H and CpRu(dcpf)H deprotonate iminium cations with acidic a-hydrogens. Cp*Ru(dppc)H is oxidized by the N-(benzylidene)pyrrolidinium cation, giving [Cp*Ru-(dppc)H]- and the vicinal diamine 1,2-bis(N-pyrrolidino)-1,2-diphenylethane. Most of the hydride complexes give rraw-dihydride cations upon protonation; an exception is [Cp*Ru(dppc)H] +, which forms a dihydrogen complex [Cp*Ru(dppc)(H2)]2+ with surprising kinetic stability. This dihydrogen complex is more acidic and less thermodynamically stable than its dihydride isomer. The H2 ligand in [Cp*Ru(dppc)-(H2)]2+ is readily replaced by nitriles; the reaction with t-BuCN occurs by a dissociative mechanism.
