formation of a bridging imido d6 Rhodium Compound by nitrene capture insertion and cycloaddition reactions
Inorganic Chemistry, 2008Co-Authors: Cristina Tejel, Miguel A Ciriano, Sonia Jimenez, Vincenzo Passarelli, Jose A LopezAbstract:The first d 6 Rhodium imido complex, [{(C 5 Me 5 )Rh(μ-NSΟ 2 C 6 H 4 Me-p)} 2 ] (2), has been obtained from the reaction of [(C 5 Me 5 )Rh(C 2 H 4 ) 2 ] with chloramine-T. Carbon monoxide inserts into the N-Rh bonds in 2 to give the dinuclear ureylene complex [(C 5 Me 5 )Rh(μ-{(Ts)N-CO-N(Ts)}Rh(CO)(C5Me5)], while the azide C 6 F 5 N 3 adds to 2 to give the mononuclear tetrazene complex [(C 5 Me 5 )Rh{(p-MeC 6 -H 4 SO 2 )N 4 (C 6 F 5 )}].

Regioselective catalytic hydrogenation of nitrogen rings of fused heteroaromatic Compounds with an iridium-triphenylphosphine complex
Catalysis Letters, 1995Co-Authors: Chong Shik Chin, Yongsun ParkAbstract:Catalytic hydrogenation of fused heteroaromatic Compounds, acridine, quinoline and quinaldine, selectively occurs at the nitrogen containing rings to give 9,10-dihydroacridine, 1,2,3,4-tetrahydroquinoline and 1,2,3,4-tetrahydroquinaldine in the homogeneous solution prepared from the reaction of [Ir(COD)(PPh_3)(PhCN)]ClO_4 (COD=1,5-cyclooctadiene) with H_2 (5 atm) at 50°C, while isoquinoline and indole are not hydrogenated under the same experimental conditions. In the presence of the Rhodium analog [Rh(COD)(PPh_3)(PhCN)]ClO_4 however, both isoquinoline and indole are also hydrogenated at the nitrogen containing rings, which is understood in terms of heterogeneous catalysis by metallic Rhodium powders produced in the reduction of the Rhodium Compound under the same experimental conditions (50°C, 5 atm of H_2).

Synthesis and reactions of tris(tetramethylethylenediaminelithium)hexamethylmetallates of Rhodium, iridium and ruthenium(III) and of hexakis(neopentyl)(μ-oxo)diRhodium(IV). X-ray crystal structures of fac-RhMe3(CO)(Me2NCH2CH2NMe2), fac-RhMe3(C4H8S)(M
Polyhedron, 1990Co-Authors: Robyn S. Hay-motherwell, Geoffrey Wilkinson, Bilquis Hussain-bates, Michael B. HursthouseAbstract:Abstract The interaction of methyllithium and the tetrahydrothiophen (THT) complexes, MCl3(THT)3 (M = Ru, Rh and Ir), in diethyl ether in the presence of tetramethylethylenediamine (TMED) gives the air- and thermally-sensitive Compounds [Li(TMED)]3 [MMe6]. The Rhodium Compound is the starting material for the synthesis of the fac-trimethyl Compounds, RhMe3(THT)(TMED), RhMe3(CO)(TMED) and RhMe3(PMe3)3; the iridium Compound fac-IrMe3(CO)(TMED) is also described. Interaction of neopentyllithium or neopentylmagnesium bromide with RhCl3(THT)3 in the presence of a source of oxygen atoms (O2 or Me3NO) gives the diamagnetic Compound, [(Me3CCH2)3Rh]2μ-O, which contains Rhodium in the IV oxidation state and a linear RhORh bond. X-ray structures of the Compounds listed in the title have been determined.
