Ruthenium-Catalyzed Isomerization of Allylic Alcohols: Oxidation State Determines Resistance Against Diene Inhibition

“…A literature method to prepare the Ru II complex 2 [12] from cis-[RuCl 2 (dmso) 4 ] and phen in CHCl 3 gave only low yields in our hands, but changing the solvent to toluene [16] resulted in direct precipitation of the pure product from the reaction mixture [see (c) in Scheme 4]. An additional and vital advantage of this method is the complete absence of bis-and tris(phen)ruthenium complexes.…”

“…C 14 H 14 Cl 3 N 2 ORuS (465.5): calcd. C 36.1, H 3.0, N 6.0, S 6.9; found C 36.9, H 2.9, N 6.0, S 7.0.cis,cis-[RuCl 2 (dmso) 2 (phen)] (2):This complex was prepared analogous to the method described in ref [16]. from cis-[RuCl 2 (dmso) 4 ] (0.20 g, 0.41 mmol) and phen (0.07 g, 0.4 mmol).…”

Synthesis and Reactivity of Ru-, Os-, Rh-, and Ir-Halide−Sulfoxide Complexes

“…64 Finally, the triply chloro-bridged diruthenium(II) complex [(dmso-S) 3 Ru(µ-Cl) 3 RuCl(dmso-S) 2 ] (16) (Chart 3) was obtained in high yield by refluxing cis,fac- (8) in wet toluene or ethanol. [65][66][67] Complex 16 has been thoroughly characterized spectroscopically, 66 and its structure was later confirmed by X-ray crystallography. 67 Conversely, the diruthenium(II) complex [(dmso-S) 3 Ru(µ-Cl)(µ-H)(µ-dmso-S,O)RuCl 2 (dmso-S)], containing the first example of an S,O bridging dmso ligand (Chart 4), was unexpectedly obtained by treatment of 8 with Na 2 (xdk) (H 2 xdk ) m-xylenediamine bis(Kemp's triacid imide)) in methanol.…”

Palladium(II) complexes of 2-pyridylmethylamine and 8-aminoquinoline: A crystallographic and DFT study

“…The bidentate N,N 0 -donor ligands 2-pyridylmethylamine (amp) and 8-aminoquinoline (amq) have been coordinated to a variety of metal centres including, but not restricted to, Pt(II), Cu(II), Zn(II), Fe(II), Ru(II), Sn(II), Cd(II), Hg(II), Cr(III) and Co(III) [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Various metal to ligand ratios have been used in the synthesis of these compounds i.e.…”

“…Despite the initial success of cis-Pt(NH 3 various Pt(II) and Pd(II) complexes with N-donor and cis-chloro ligands were synthesised in order improve drug efficacy and overcome drug resistance [1,2]. Coordination complexes of amp and amq formed part of these studies.…”
