TOLUENE-SOLVATED RHODIUM ATOMS: EVIDENCE FOR A HYDRIDORHODIUM COMPLEX

The codeposition of rhodium with toluene affords on melting a red brown solution, stable up to -50 deg C, which contains a hydridorhodium product, as shown by (1)H NMR analysis and isolation of hydrido complexes by reaction with phosphines.

Synthesis of thiiranes by rhodium-catalyzed sulfur addition reaction to reactive alkenes

A rhodium complex derived from RhH(PPh3)4, dppe, and 4-ethynyltoluene catalyzes the addition reaction of sulfur to norbornenes giving the corresponding thiiranes under acetone reflux conditions. The rhodium complex effectively transfers a sulfur atom to the double bond from sulfur, and exo-adducts are obtained. The reaction is also applicable to (E)-cyclooctene and cyclic allenes. The ring-opening reaction of the thiiranes with lithium aluminium hydride gives the corresponding thiols. This journal is

Structure and reactivity of dimeric rhodium(i) formate complexes: X-ray crystal structure analysis of [{(cod)rh(μ-κ2o,o′-hco2)}2] and phosphane-induced hydride transfer to give an η3-cyclooctenyl complex

The X-ray crystal structure analysis of [(L2)Rh(μ-κ2O,O′-HCO2)2Rh(L′2)] 1a (L2 = L′2 = cod) is reported. Complex 1a reacts with CO to form 1c (L = L′ = CO) via the intermediate 1b (L2 = cod, L′ = CO). 1a and 1c do not incorporate 13CO2 or D2 in the formate moiety and are poor catalysts for CO2 hydrogenation to formic acid. Reaction of la with the chelating phosphanes R2P(CH2)2PR2 (R = Ph, iPr, Cy) 3a-c leads to replacement of the diolefin ligand and cleavage of the dimeric structure under formation of monomeric complexes [(3a-c)2Rh][HCO2] 4a-c. 4a was isolated in up to 78% yield and complexes [(3a)2RhH] 5a and [(3a)Rh(η3-C8H13)] 6a were detected as side products. Complexes of type 6 are formed exclusively under identical reaction conditions using the bidentate ligand Ph2P(CH2)3PPh2 3d or monodentate ligands PAr3 3e-f. A possible mechanism for the formation of complexes 4, 5 and 6 is discussed involving hydride transfer from the HCO-2 ligand to Rh and subsequently to coordinated cod.
