Synthesis, structure, and ligand-promoted reductive elimination in an acylrhodium ethyl complex

8-Quinolinecarboxaldehyde and [(C2H4)2RhCl]2 reacted to give a polymeric acylrhodium ethyl compound which was solubilized by pyridine to give chloroethyl(8-quinolinecarbonyl-C,N)(pyridine)rhodium. This compound was stable in the presence of amine ligands, but phosphine ligands caused rapid reductive elimination. Intermediates in the reductive elimination were observed at -40°C by using 1H, 13C, and 31P NMR in the case of the ligand PPh3. In the first-formed intermediate PPh3 displaced pyridine. The resulting five-coordinated Rh(III) complex reductively eliminated (with an observed first-order rate constant of 3.7 × 10-4 s-1 at -40°C) to give an η2-ketone Rh(I) intermediate. With excess phosphine RhCl(PPh3)3 and 8-quinolinyl ethyl ketone were the final products. Recrystallization of the starting pyridine complex from pyridine-ether gave Cl(C2H5)Rh(C10H6NO)(C 5H5N)2·1/2C 4H10O (chloroethyl(8-quinolinecarbonyl-C,N)bis(pyridine)rhodium-hemi(diethyl ether)), whose structure was determined by single-crystal X-ray diffraction. The compound crystallizes in the triclinic space group P1 with two molecules in the unit cell a = 8.933 (3) A?, b = 17.573 (8) A?, c = 7.760 (2) A?, α = 97.57 (3)°, β = 98.04 (2)°, and γ = 79.98 (3)°. The least-squares refinement with anisotropic thermal parameters for all non-hydrogen atoms converged at RF = 0.046 (RwF = 0.055) for 2595 observed reflections and 262 parameters refined.

The preparation and nuclear magnetic resonance spectra of hydridophosphine complexes of ruthenium and rhodium

The preparations of the complexes H2Ru((C6H5)2PCH3) 4, H2Ru(CO)C((6H5)2PCH 3)3 HRh((C6H5)3P)4, HRh((C6H5)3P)4, HRh((C6H5)3P)3, HRh((C6H5)2PCH3)4, ((C6H5)2PCH3)3RhCl, and ((C6H5)2PCH3)2(CO)RhCl are described. The nmr spectra of these complexes are discussed with regard to possible structures. The results confirm a rapid ligand exchange in these types of compounds.
