The ruthenium complexes show high activity as catalysts in the hydrogenation reaction of N-benzylideneaniline and the hydrogen transfer reaction. The products of the catalysis were obtained with conversions between 21 and 91% after 2 h of reaction. The Ru(phen)(CO) 2Cl 2 complex was the catalyst that showed the highest conversion (91%) for the hydrogenation of N-benzylideneaniline. The complexes Ru(dppz)(PPh 3) 2Cl 2, Ru(bpy)(PPh 3) 2Cl 2 and Ru(dppz)(CO) 2Cl 2 showed 99% conversion in the hydrogen transfer reaction. © 2012 Elsevier B.V.
