Abstract: The trans form of the title complex was synthesized in high yield by interaction of equimole RuCl2(Ph3P)4 or RuCl2(DMSO)4(DMSO=dimethylsulfoxide)with P2N2(i.e.= N,N'-bis[o-(diphenylphosphine benzylidene)]ethylene diamine)in refluxing toluene. The complex has been investigated as catalyst for selective hydrogenation of α,β-unsaturated acids and some functionalized olefins. The hydrogenation catalytic activity was observed as follows: styrene>acrylic acid>benzaldehyde>salicyl aldehyde>cyclohexanone>furfural>methylacrylic acidacetophenone. The effect of addition of NH4PF6 or AgNO3 as promotor has also been studied.

Key words: diiminodiphosphine ligand, ruthenium complex, synthesis, hydrogenation, catalytic activity
