Syntheses, structures and reactivity of dinuclear organoruthenium-nickel complexes with N,N′-bis(2-thiobenzylidene)-1,2-phenylenediaminato (tsalphen) ligand.

Treatment of metalloligand [Ni(tsalphen)] (tsalphen =  N , N ′-bis(2-thiobenzylidene)-1,2-phenylenediaminato) with [( η 6 - p -cymene)RuCl( μ -Cl)] 2 or [CpRu(PPh 3 ) 2 Cl] afforded cationic “Ni( μ -S) 2 Ru” bimetallic complexes [( η 6 - p -cymene)Ru{Ni(tsalphen)}(MeCN)](OTf) 2 ( 1 ) and [CpRu{Ni(tsalphen)}(PPh 3 )] 2 (NiCl 4 )⋅4MeOH ( 2 ), respectively, which are characterized by single-crystal X-ray diffraction, and their catalytic activity for acetalation of benzaldehyde in the presence of H 2 was also investigated.
