In the presence of further NHC, the bis-carbene dihydrido species Rh(H)(2)Cl(NHC)(2) are formed; a crystal structure of the IPr complex 5 is analogous to that of the known IMes analogue. The dihydride-mixed-carbene species Rh(H)(2)Cl(IPr)(IMes) (5a) was also observed but not isolated. A benzene solution of 5 under D-2 slowly generates the corresponding dideuteride. Reactions of the mono-carbenes (1/3, or 2/4) with CO in hexane afford the respective dicarbonyl complexes RhCl(CO)(2)(NHC) [NHC = IPr (6), IMes (7)], while CO reactions with the bis-carbene dihydrides give, respectively, the mono-carbonyl complex RhCl(CO)(IPr)(2) (8) and the known IMes analogue. All the complexes are characterized by elemental analysis, H-1 and C-13{H-1} NMR and IR spectroscopies and, in the case of 5, by X-ray crystallography. The catalytic activities of 5 and the previously reported Rh(H)(2)Cl(IMes)(2) for hydrogenation of COE and 1-octene (and isomerization of the latter) are shown to be poor.

	abstract = {A new family of rhodium-diene based complexes has been developed that incorporates an N-heterocyclic carbene ligand with an N-donor tether. The ligand is denoted (Mes)[CNH] 2 (where (Mes)[CNH] is 2,4,6-Me3C6H2NC3H2NCH2CH2NH-2,4,6-Me3C6H2) and (Mes)[CN] for the amido form. The synthesis of the (Mes)[CNH] ligand involves reaction of N-mesitylimidazole with 2-chloroethyl-N-mesitylamine under melt conditions, followed by deprotonation with KN(SiMe3)(2). The reaction of (Mes)[CNH] with [(diene)RhCl](2) results in the formation of the monodentate complexes, (Mes)[CNH]Rh(diene)Cl (where diene = 1,5-cyclooctadiene (COD): 3a; diene = 2,5-norbornadiene (NBD): 3b). Bidentate variants could be isolated as either a neutral species, (Mes)[CN]Rh(diene) 4a-4b, via deprotonation, or an ionic analogue such as [(Mes)[CNH]Rh(diene)]BF4 5a-5b by reaction with NaBF4. Compounds 4-5 are the first examples of rhodium compounds that contained a bidentate NHC ligand with a pendant amino or amido donor. Complexes 3-5 were characterized fully and the solid-state single crystal X-ray structures of 3a, 4a, and 5b are discussed. The utility of these complexes as catalyst precursors for hydrogenation reactions was examined and it was determined that these systems are not significantly more active than colloidal rhodium when parallel reactions were run. Various methods of transfer hydrogenations were also investigated with 3a, which did not yield an appreciable conversion of either benzophenone or N-benzylideneaniline as substrates.},

Precipitation of 3 from the MeOH solution, even under H-2, causes sequestration of the Rh and complete suppression of the catalytic activity. (In a previously studied system with the corresponding, non-hydroxy-substituted ketimine, PhC(Me) = NCH2Ph, the Rh was sequestered as an inactive o-metalated species). The solid state structure of 3 is retained in CH2Cl2 solution, but in MeOH and Me2CO reversible loss of the ketimine generates the cis-[Rh(PPh3)(2)(solvent)(2)]PF6 species. (c) 2006 Elsevier B.V.

Reaction of the tridentate amidophosphine ligand precursor [NPN]Li-2(THF)(2) (where NPN is PhP(CH2SiMe2NPh)(2)) with [RuCl2(cod)](x) results in the formation of two diastereomeric complexes of the formula [NPNH]Ru(eta(3):eta(2)-C8H11), wherein the cyclooctadiene ligand has been deprotonated by the ancillary ligand to generate a cyclooctadienyl unit. These Ru(II) complexes are five-coordinate with a bidentate PN ligand and a dangling amine unit. The diastereomers are in equilibrium, as shown by variable-temperature NMR studies. The fluxional process that interconverts diastereomers involves proton transfer from the dangling amine arm to the amido unit, a process that equilibrates the two ends of the tridentate NPN ligand on the chemical time scale. Deprotonation of the amine arm by MN(SiMe3)(2) generates a series of ruthenate complexes of the formula [M(THF)]([NPN]Ru(eta(3):eta(2)-C8H11)), where M = Li or Na. Addition of Me3SiCl results in the formation of new diastereomers that contain silylated dangling arms, and these diastereomers do not interconvert.},

At high nitrile concentrations, the principal species present is RuCl(PP)(RCN)(3)X-+(-) (X = Cl); the cation can generally be isolated (as the PF6 salt) by abstraction of the chloride counterion with NH4PF6. Use of 2 equiv of NH4PF6 generates Ru(PP)(RCN)(4)(2+)(PF6-)(2) (PP = dppb). In the absence of a halide-abstracting agent, addition of hexanes or diethyl ether precipitates neutral RuCl2(PP)(RCN)(2) species, which undergo further loss of nitrile in the solid state (R = Me) or in solution (R = Me, Ph). Redissolution of the neutral species in chlorocarbon solvents gives Ru2Cl3(PP)(2)(RCN)(2)X-+(-) (X = Cl) and, in benzene, Ru2Cl4(PP)(2)(RCN). The dinuclear cation (X = PF6) is also accessible by reaction of RuCl(PP)(RCN)(3)+PF6- with CH2Cl2 or CDCl3, while the mononitrile can be obtained directly by reaction of Ru2Cl4(PP)(2) or RuCl2(PP)(PPh3) with small amounts of nitrile in benzene.},

The homogeneous systems were initially dominated by ones based on Rh complexes containing chiral, chelating diphosphine ligands, although related Ru-and Ir-based systems are becoming more prominent; a very recent, extremely effective hydrogen transfer system (from formic acid), based on Ru catalysts containing chiral 1,2-diamine ligands, is especially significant. A fundamentally different type involving an early transition-metal catalyst (a chiral titanocene) has been reported. Enantiomeric excess (e.e.) values in the range of 90-100\% have now been achieved with certain substrates. Emphasis is given to some Rh and Ru catalysts developed in the Department of Chemistry, The University of British Columbia (UBC). Factors discussed include: dependence of conversions, rates and e.e. values on substrate and catalyst type; kinetic dependences; and mechanistic insights, especially possible roles of intermediate metal-hydride and -imine species.},

The diphosphines (PP) used include chiral (chiraphos, diop, binap) and achiral (dppe, dppb) systems (chiraphos = Ph2PCH(Me)CH(Me)PPh2; diop = Ph2PCH2CHOCMe2OCHCH2PPh2; binap = 2,2{\textquoteright}-bis(diphenylphosphino)-1,1{\textquoteright}-binaphthyl; Ph2P(CH2)(n)PPh2 (n = 2, dppe; n = 4, dppb)). Activity was observed in MeOH at low catalyst concentrations (0.77 mM Ru), under moderate conditions (room temperature (r.t.), 1000 psi H2). The air-stable Ru2Cl5(PP)2 complexes were more active than the commonly used dimeric Ru2(II,II) systems to which they give rise in situ. Asymmetric induction in the prochiral ketimine PhCH2N = C(Me)Ph was consistent, though modest, within the diop and binap series of neutral complexes, implying a common catalytic intermediate within each series. A maximum e.e. of 27\% was found using Ru2Cl5(chiraphos)2 as catalyst; this represents a non-optimized figure for asymmetric induction, as no other prochiral ketimines were screened.},
