New Tetranuclear Ruthenium(I) Carbonyl Trifluoroacetate Complex: Gas-Phase Transformations and Coordination Reactions

Metal–Ligand Cooperation on a Diruthenium Platform: Selective Imine Formation through Acceptorless Dehydrogenative Coupling of Alcohols with Amines

“…The compounds Ru 2 (CO) 4 (CH 3 COO) 2 , BIN ⋅ HBr, and PIN ⋅ HBr were synthesized by following the literature procedures 13. 14, 30 Benzyl alcohol‐α,α‐[D] 2 was purchased from Sigma‐Aldrich and used without further purification.…”

Ru4(CO)8(μ-OOCAd)4(PPh3)2: Phosphine Derivative of an Electron-Deficient Linear Tetraruthenium Cluster

“…2 Single-crystal X-ray structural analysis of these for R = CF 3 , for example, showed that they comprised dinuclear [Ru 2 (CO) 4 (μ-OOCCF 3 ) 2 ] units held together by strong interactions between an O atom of the carboxylato bridge and an Ru atom of the neighboring unit. 3 These polymers dissolved reversibly in coordinating solvents (L), such as acetonitrile and tetrahydrofuran, to form dinuclear complexes Ru 2 (CO) 4 (μ-OOCR) 2 L 2 (Scheme 1). The single-crystal X-ray structural analysis of Ru 2 (CO) 4 (μ-OOCF 3 ) 2 (NCMe) 2 , for example, showed that it comprised a diruthenium unit bridged by two mutually cis carboxylate groups and with the acetonitriles occupying axial positions.…”

“…Phosphine derivatives have also been obtained, and they have a similar structure. 5 Much of the recent work on this class of compounds has been carried out by the group of Petrukhina, 3,6 who have developed solvent-free synthetic routes to them. The propensity of these polymeric complexes to form the coordinatively unsaturated, and electron-deficient, diruthenium [Ru 2 (CO) 4 (μ-OOCR) 2 ] units has also been exploited in catalytic investigations.…”

Sawhorse-type diruthenium tetracarbonyl complexes

“…The chain arrangement of the dinuclear units by staggered ruthenium-oxygen interactions was finally confirmed by a single-crystal X-ray structure analyses of the benzoato derivative [Ru 2 (CO) 4 (OOCPh) 2 ] n [7], similar to the carbonyl-free polymer [Ru 2 (OOCPh) 5 (Fig. 6) [9].…”

“…Dimers of dinuclear Ru 2 (CO) 4 . Structure of a fragment of the polymeric chain in [Ru2(CO)4(OOCCF3)2]n, the fluorine atoms being omitted for clarity [9]. ruthenium-oxygen bonds, the terminal positions being occupied either by carbonyl or by sec-butyric acid ligands, see Fig.…”
