Chloride substitution of [CpRu(dppf)Cl] with sulfur-containing ligands

Reactivity of [CpCr(CO)3]2 towards thione (CS) moieties in some sulfur-containing substrates

“…In the absence of a sulfur-abstractor, we have previously obtained a VTTC-coordinated ruthenium complex (Scheme 9) [16], which involves chloride substitution in [CpRu(dppf)Cl] by VTTC.…”

Synthetic, X‐ray Diffraction, Electrochemical, and Density Functional Theoretical Studies of (Indenyl)ruthenium Complexes Containing Dithiolate Ligands

“…In a recent study, Veiros et al demonstrated that the effect of the nature of the coligands on the strength of the indenyl-metal bond plays an important role in the energetics of η 5 versus η 3 indenyl-molybdenum complexes. [19] Because of the constraints on computational time, we have selected the complexes [(Ind)Ru(L) 2 (S 2 COMe)] (H1: L = PMeH 2 , H2: L = PH 3 , H3: L = CO), containing small phosphane ligands such as PH 3 and PH 2 Me, rather than the larger diphos ligands (dppm or dppf), as the model compounds for study. In this series, complex H1 contains the strongest σ-donor ligand, followed by H2, with H3 possessing the strongest π-acceptor ligand.…”

“…[1] Our work on some of these ligands was directed at their reactivity in the coordination environment of CpCr(CO) n (n = 2 or 3), [2] (HMB)Ru(dppf), and CpRu(dppf) (Cp = η 5 -C 5 H 5 and HMB = η 6 -C 6 Me 6 ). [3] A logical and interesting follow-up of these studies on Ru would be a corresponding reactivity study of the indenyl (Ind) analogue, as Ind can potentially assume bonding modes involving η ring slippage to η 3 or η 6 -C 9 H 7 . [4] Such an investigation is also timely, as there is intense interest in reactivity aspects of (Ind)Ru complexes, especially from catalytic perspectives; [5] and the bulk of the literature on (Ind)Ru complexes deals with examples containing phosphanes as coligands, with only two such complexes carrying S-donor ligands, viz.…”

Synthesis, X‐ray Crystal Structures and Electrochemistry of (Indenyl)ruthenium Complexes Containing dppf and Heterocyclic Thiolato/Thione Ligands

“…(Scheme 2). [10] The reaction with HSbztz, (route b) resulted in Cl -displacement, giving [Ru(dppf)-(ind)(Sbztz)] (4) in 60 % yield, with no byproduct indicative of Ind ligand dissociation. With HSmtdz, the reaction yielded an ionic product, [Ru(dppf)(Hmtdzt)(ind)]Cl [5]Cl (route c).…”

“…[11] www.eurjic.org In complex 4, the Ru1-S1 distance [2.4086(9) Å] is in the normal range for the Ru-S bond length. [10,12,13] The long N1-Ru1 distance (3.676 Å) is clearly indicative of the absence of any interaction between the two atoms [cf. N-Ru 2.242(6) Å for the bidentate Sbztz ligand].…”
