Ruthenium(η6,η1-arene-CH2-NHC) Catalysts for Direct Arylation of 2-Phenylpyridine with (Hetero)Aryl Chlorides in Water

“…The dihedral angle between benzimidazolylidine and tetramethylbenzyl rings is 84.49 (16)°. The Ru-carbene distance, Ru(1)–C(1), of 2.040(3) Å, matches the literature data [ 52 , 53 , 54 ]. The Ru(1)–Cl(1) and Ru(1)–Cl(2) single bond lengths are 2.4267(9) and 2.4222(8) Å.…”

“…The Ru(1)–Cl(1) and Ru(1)–Cl(2) single bond lengths are 2.4267(9) and 2.4222(8) Å. The values of the geometrical parameters of compound 2b agree with those reported for similar compounds [ 52 , 53 , 54 ].…”

“…The complex is best described as containing an octahedrally coordinated Ru center with the arene residue occupying three sites, the remaining sites being occupied by an Ru–C(carbene) bond, derived from the benzimidazole ring, and two Ru–Cl bonds. The small steric demand of the benzimidazolylidene ligand is reflected in the C(1)–Ru(1)–C(13), C(1)–Ru(1)–Cl(1) and C(1)–Ru(1)–Cl(2) angles of 78.59(12), 92.94(9) and 89.64(8)°, respectively, a result that reflects the situation we found in related Ru complexes ( Table 2 ) [ 52 , 53 , 54 , 55 ]. The atoms comprising the tetramethylbenzyl ring are coplanar, the mean deviation from their least squares plane being 0.017(2) Å.…”

“…In previous papers, we have described the synthesis, characterization and applications of palladium, platinum and ruthenium N-heterocyclic carbene complexes as catalysts (Yaşar et al, 2008;Arslan et al, 2007Arslan et al, , 2005aArslan et al, , 2005bÖzdemir et al, 2008, 2005. In view of these important attributes of Nheterocyclic carbene derivatives, we report here the crystal structure of one of them.…”

Bromido[1-(η6-4-tert-butylbenzyl)-3-(2,4,6-trimethylbenzyl)benzimidazol-2-ylidene]chloridoruthenium(II)

“…Previous work from our research groups in this area has focused on the elaboration of olefins as electron-rich heterocyclic carbene precursors to allow the formation of chelating carbenes. We have also looked at the rapidly developing chemistry of η 6 -arene ruthenium(II) complexes containing substituted imidazolidin-2-ylidenes (Özdemir et al, 2001; Çetinkaya et al, 2001, 2002, 2003), and on synthesis, characterization, crystal structure, and using palladium, platinum and ruthenium N-heterocyclic carbene complexes as catalysts (Yaşar et al, 2008;Arslan et al, 2007aArslan et al, , 2007bArslan et al, , 2007cArslan et al, , 2004aArslan et al, , 2004bArslan et al, , 2005aArslan et al, , 2005b.…”
