; The title complex was obtained by reacting [(eta(6)-C6H6)(eta(6)-C6Me6)(2)Ru-3(mu(2)-H)(3)(mu(3)-O)(+) with RuCl3 . nH(2)O in aqueous solution. it crystallises as the tetrafluoroborate salt. The cationic cluster is formed of two tetrahedral Ru-4 substructures which are held together by two chloro bridges. (C) 2002 Elsevier Science B.V.

; Ward, Thomas R.In situ high-pressure NMR spectroscopy of the hydrogenation of benzene to give cyclohexane, catalysed by the cluster cation [(η6-C6H6)(η6-C6Me6)2Ru3(μ3-O)(μ2-OH)(μ2-H)2]+2, supports a mechanism involving a supramolecular host-guest complex of the substrate molecule in the hydrophobic pocket of the intact cluster molecule. - PublicationAccès libreCatalytic hydrogenation of aromatics under biphasic conditions: isolation and structural characterisation of the cluster intermediate [(η6-C6Me6)2(η6-C6H6)Ru3(μ2-H)2(μ2-OH)(μ3-O)]+(2001-03-01)
; The water-soluble cluster cation [(η6-C6Me6)2(η6-C6H6)Ru3(μ2-H)3(μ3-O)]+ (2) catalyses the hydrogenation of benzene and benzene derivatives to give the corresponding cyclohexanes under biphasic conditions. The catalytic activity of 2 depends markedly on the substrate, an extremely high activity being observed for ethylbenzene. The cationic species present in the catalytic mixture of the ethylbenzene hydrogenation could be isolated as the tetrafluoroborate salt and characterised as the cation [(η6-C6Me6)2(η6-C6H6)Ru3(μ2-H)2(μ2-OH)(μ3-O)]+ (3). With 3 as the catalyst, the catalytic activity is also much higher for other benzene derivatives. - PublicationMétadonnées seulementReactions of the cluster anion [HRu3(CO)(11))](-) with dicyclohexylphosphine: Synthesis and molecular structure of H2Ru3(CO)(8)(PCy2)(2) and H2Ru3(CO)(6)(PCy2)(2)(HPCy2)(2)(2001)
; - PublicationMétadonnées seulementReactions of the cationic complex [(eta(5)-C5Me5)(2)Ir-2(mu(2)-H)(3)](+) with nitrogen-containing heterocycles in aqueous solution(2001)
; The dinuclear cation [(eta (5)-C5Me5)(2)Ir2(mu (2)-H)(3)](+) (1) reacts in aqueous solution with pyrazole and 4-methylpyrazole to give the bispyrazolato complexes [(eta (5)-C5Me5)(2)Ir-2(mu (2)-H)(mu (2)-eta (1),eta (1)-N2C3H2R)(2)](+) (R = H, 2; R = Me, 3). The reaction of complex 1 with 1,2,4-triazole results in the formation of the bistriazolato complex [(mu (5)-C5Me5)(2)Ir-2(mu (2)-H)(mu (2)-eta (1),eta (1)-N3C2H2)(2)](+) (4). Successive protonation of the triazolato ligands in 4 leads to the complexes [(eta (5)-C5Me5)(2)Ir-2(mu (2)-H)(mu (2)-eta (1),eta (1)-N3C2H2)(mu (2)-eta (1),eta (1)-N3C2H3)](2+) (5) and [(eta (5)-C5Me5)(2)Ir-2(mu (2)-H)(mu (2)-eta (1),eta (1)-H3C2H3)(2)](3+) (6). The reaction of 1 with 1,2,3-triazole gives a 1:1 mixture of the bistriazolato complexes [(eta (5)-C5Me5)(2)Ir-2(mu (2)-H)(mu (2)-eta (1),eta (1)-N3C2H2)(2)](+) with parallel (7a) and antiparallel (7b) coordination of the triazolato ligands. The X-ray structure analysis of 3 reveals a diiridium backbone which is bridged by two pyrazolato ligands, the N-N axis being coordinated in a mu (2)-eta (1),eta (1) fashion.
