Synthesis of novel ruthenium complexes of 2,2′-bis(diphenylphosphinomethyl)-1,1′-biphenyl and their catalytic hydrogenation reactions to α,β-unsaturated aldehydes

Three ruthenium complexes containing BISBI [2,2′-bis(diphenylphosphinomethyl)-biphenyl], RuCl2(PPh3)(BISBI) 1, RuHCl(CO)(PPh3)(BISBI) 2 and RuH2(CO)(PPh3)(BISBI) 3, had been prepared. Their compositions and structures were characterized by 31P{1H}-NMR, 1H-NMR and elemental analysis. Results of 31P{1H}-NMR showed that the PPh3 in complex 1 was completely dissociated and a dimer complex [RuCl2(BISBI)]2 was generated in CDCl3 and C6D6 solutions. Molecular structure of 3 was also confirmed by single-crystal X-ray diffraction, the crystal belonged to a monoclinic system, P21/n space group, a=16.771(3) A, b=20.688(4) A, c=17.139(3) A, β=106.03(3)°, V=5715(3) A3 and Z=4. The hydrogenation results revealed that the three complexes showed much higher activities and selectivities than their analogous triphenylphosphine complexes for the hydrogenation of C=O bond in citral (3,7-dimethyl-2,6-octadienal) and cinnamaldehyde.
