Olefin isomerization reactions catalyzed by ruthenium hydrides bearing Schiff base ligands
A series of in situ-generated ruthenium hydride complexes Ru(PPh 3)2(CO)H(Ln) (n = a-h) incorporating a Schiff base ligand was investigated for the isomerization of olefins. 1H-NMR was used to characterize the new hydride species in combination with 31P-NMR. Allylbenzene and 1-octene were used as model substrates. Temperature, solvents and catalyst/substrate mole ratio were taken into account as parameters to optimize the isomerization reaction. All catalysts showed the best performance in 2-butanol, suggesting that the catalytic activity depends not only strongly on the steric and electronic environment of the ruthenium but also on the chosen solvent.

Assignment and conformational investigation of asymmetric phenylindenylidene ruthenium complexes bearing N, O-bidentate ligands
The NMR conformational study of three asymmetric phenylindenylidene ruthenium complexes 4.1-4.3, is presented. Complete 1H and 13C assignments could be obtained for 4.1-4.3 in benzene solution from multiple 2D homonuclear and heteron
