Abstract
A series of in situ-generated ruthenium hydride complexes Ru(PPh3)2(CO)H(Ln) (n = ah) 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.
