Selective hydrogenation of ruthenium acylphosphine complexes

Hydrogenation of a benzene ruthenium chloride dimer in the presence of novel acylphosphine (phosphomide) ligands resulted in the formation of corresponding ruthenium(II)-benzyl phosphine complexes. Here, selective reduction of the carbonyl group to a methylene unit takes place with molecular hydrogen under mild conditions in good yield. This approach provides an alternative synthesis of ruthenium phosphine complexes of benzyl and heterobenzyl phosphine ligands.

Regiochemical effects on molecular stability: A mechanochemical evaluation of 1,4- and 1,5-disubstituted triazoles

Poly(methyl acrylate) chains of varying molecular weight were grown from 1,4- as well as 1,5-disubstituted 1,2,3-triazoles. Irradiating acetonitrile solutions of these polymers with ultrasound resulted in the formal cycloreversion of the triazole units, as determined by a variety of spectroscopic and chemical labeling techniques. The aforementioned reactions were monitored over time, and the rate constant for the cycloreversion of the 1,5-disubstituted triazole was measured to be 1.2 times larger than that of the 1,4-disubstituted congener. The difference was attributed to the increased mechanical deformability of the 1,5-regioisomer as compared to the 1,4-isomer. This interpretation was further supported by computational studies, which employed extended Bell theory to predict the force dependence of the activation barriers for the cycloreversions of both isomers.

Bridging and terminal half-sandwich ruthenium dinitrogen complexes and related derivatives: A structural study

The reaction of [CpRuCl(P)2] [(P)2 = dippe (1,2-bis(diisopropylphosphino)ethane; (PEt3)2; (PMeiPr2)2] with Na[BAr?4] (Ar?4 = 3,5-bis(trifluoromethyl)phenyl) in fluorobenzene under argon generates the corresponding cationic 16-electron species [CpRu(P)2]+, which reacts with trace amounts of dinitrogen present even in high-purity argon furnishing the dinitrogen-bridged complexes [{CpRu(P)2}2(mu-N2)][BAr?4] 2 [(P)2 = dippe 1a; (PEt3)2 1b; (PMeiPr2)2 1c]. If the reaction is performed under dinitrogen, the terminal dinitrogen complexes [CpRu-(N2)(P)2][BAr?4] [(P)2 = dippe 2a; (PMeiPr2)2 2c] are obtained. Compound 1b was obtained irrespectively of the atmosphere used, and no terminal dinitrogen complex has been detected. The crystal structures of 1a, 1b, and 2a have been determined. During one attempt to isolate the 16-electron complex [CpRu(PMeiPr2)2][BAr?4], the 18-electron tris(phosphine) derivative [CpRu(PMeiPr2)3][BAr?4], 3, was obtained instead, and it was structurally characterized. Halide abstraction from [CpRuCl(PMeiPr2)(PPh3)] under dinitrogen using Na[BAr?4] yielded [CpRu(N2)(PMeiPr2)(PPh3)] [BAr?4], 2d, but under argon the complex [CpRu(PMeiPr2)(PPh3)]-[BAr?4], 4, which contains a rare eta3-coordinated PPh3 ligand as shown by X-ray crystallography, was isolated.

Synthesis, electrochemistry, and reactivity of half-sandwich ruthenium complexes bearing metallocene-based bisphosphines

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.
