    Dichloride[1-(2,4,6-trimethylbenzyl)-3-(biphenyl-2-ylmethyl) -imidazolidin-2-ylidine (?6-hexamethylbenzene)]ruthenium
    (2006) Arslan H.; Van Derveer D.; Özdemir I.; Yaşar S.; Çetinkaya B.
    The single crystal X-ray structure of the imidazolidin ruthenium complex, C38H46N2Cl2Ru, was determined. The complex is an orthorhombic space group Pbca with a = 17.3586(32) Å, b = 14.4447(27) Å, c = 27.4325(52) Å, and V = 6878.466(4) Å3 with Z = 8 for Dcalc = 1.357 g/cm3. It exhibits the expected 3-legged piano stool geometry. There is one coordination bond of the ruthenium atom with the electrons of the ?6-hexamethylbenzene, 2 symmetrical Ru-Cl bonds, and one Ru-C bond involving the imidazole ring. The coordination around the ruthenium atom is 4-fold, which in this is case is pseudo-tetrahedral. © TÜBİTAK.

    Ruthenium(?6,?1-arene-CH2-NHC) catalysts for direct arylation of 2-phenylpyridine with (hetero)aryl chlorides in water
    (MDPI, 2018) Glu N.K.; Zdemir I.; Gürbüz N.; Arslan H.; Dixneuf P.H.
    A series of new benzimidazolium halides were synthesized in good yields as unsymmetrical N-heterocyclic carbene (NHC) precursors containing the N–CH2–arene group. The benzimidazolium halides were readily converted into ruthenium(II)–NHC complexes with the general formula [RuCl2(?6,?1–arene–CH2–NHC)]. The structures of all new compounds were characterized by 1H NMR (Nuclear Magnetic Resonance), 13C NMR, FT-IR (Fourier Transform Infrared) spectroscopy and elemental analysis techniques. The single crystal structure of one benzimidazole ruthenium complex, 2b, was determined. The complex is best thought of as containing an octahedrally coordinated Ru center with the arene residue occupying three sites, the remaining sites being occupied by a (carbene)C–Ru bond and two Ru–Cl bonds. The catalytic activity of [RuCl2(?6,?1–arene–CH2–NHC)] complexes was evaluated in the direct (hetero)arylation of 2-phenylpyridine with (hetero)aryl chlorides in water as the nontoxic reaction medium. These results show that catalysts 2a and 2b were the best for monoarylation with simple phenyl and tolyl chlorides. For functional aryl chlorides, 2d, 2e, and 2c appeared to be the most efficient. © 2018 by the authors.
