Resumen
The synthesis and characterization of ruthenium complexes containing polypyridine ligands: Ru(dppz)(PPh3)(2)Cl-2. Ru(bpy)(PPh3)(2)Cl-2, Ru(phen)(PPh3)(2)Cl-2. Ru(dppz-Cl)(PPh3)(2)Cl-2, Ru(phen)(CO)(2)Cl-2, Ru(bpy)(CO)(2)Cl-2 and Ru(dppz)(CO)(2)Cl-2 (where dppz: dipyrido[3,2-a:2',3'-c]phenazine, dppz-Cl: 10-chlororodypirido[3,2-a:2',3'-c] phenazine, phen: 1,10-phenanthroline and bipy: 2,2'-bipyridine) are reported. 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)(2)Cl-2 complex was the catalyst that showed the highest conversion (91%) for the hydrogenation of N-benzylideneaniline. The complexes Ru(dppz)(PPh3)(2)Cl-2, Ru(bpy)(PPh3)(2)Cl-2 and Ru(dppz)(CO)(2)Cl-2 showed 99% conversion in the hydrogen transfer reaction.
