Dichlorido(η6-p-cymene)(ethoxydiphenylphosphane)ruthenium(II)

“…The structure of complex 1 reported here adopts the classic piano stool structure with a pseudo-tetrahedral arrangement of the p-cymene, chloride anions and the phosphane about the ruthenium metal center. The bond lengths and angles about the Ru core compare well with 2 (Albertin, et al, 2010) and 3 (Elsegood, et al, 2006), which have been investigated previously ( Table 1). The average Ru -C distance is 2.217 (3) Å, which is very similar to the previously reported Ru -C distances of 2.218 (4) Å and 2.218 (2) Å for 2 and 3, respectively.…”

“…These catalysts have been found to be susceptible to poisoning by cyanide, which forms when cyanohydrins decompose in aqueous solutions. The title compound [Ru(η 6 -p-cymene)Cl 2 PPh 2 OEt] (1), as well as the similar compounds [Ru(η 6 -pcymene)Cl 2 PPhOEt 2 ], (Albertin, et al, 2010), 2, and [Ru(η 6 -p-cymene)Cl 2 PPh 3 ] (3), (Elsegood, et al, 2006), have been used previously to hydrate nitriles in aqueous solutions, where addition of surfactant was used to increase the solubility of the catalyst by promoting the formation of micelles (Cavarzan, et al, 2010). It was hypothesized that a hydrophobic catalyst would be resistant to cyanide poisoning under biphasic conditions, because the cyanide would be in the aqueous phase and the catalyst in the organic phase.…”

Synthesis, Structure, Reactivity, and Catalytic Activity of Cyclometalated (Phosphine)‐ and (Phosphinite)ruthenium Complexes

“…The structure of 7 is depicted in Figure ; it exhibits a structure similar to that of 1b . The Ru(1)–P(1) bond [2.3427(7) Å] is in good agreement with that in ( p ‐cymene)Ru(PPh 3 )Cl 2 [2.3438(6) Å], and a little shorter than that in 1b [2.4034(7) Å].…”

Anti-tumour active gold(i), palladium(ii) and ruthenium(ii) complexes with thio- and selenoureato ligands: a comparative study

“…34 The distances between the ruthenium atom and the centre of the arene rings (S 1.745 Å, Se 1.746 Å) are typical for such η 6 -arene ruthenium compounds. 48 The palladium complexes ( Fig. 3) show square-planar coordination with one bidentate chalcogenoureato and a 1,10-phenanthroline ligand bound to the metal.…”
