Pentacarbonyl (n2-tetracyanoethylene) metal(O) com plexes o f chrom ium , m olybdenum and tung sten have b een synthesized by the photochem ical reaction o f hexacarbonyl metal(O) with te tra cyanoethylene in tolu en e at room tem perature. TTie com plexes w ere purified by chrom atography and recrystallization, and characterized by UV- visible, IR and 13C N M R spectroscopy. T etra cyanoethylene is sym m etrically bonded to the M (C O )5 unit through its c a rb o n -c a rb o n double bond as an ^ 2-ligand. T he spectral data are dis cussed in term s of the m e ta l—»ligand tc inter action.

Synthesis and Spectroscopic Studies of Pentacarbonylfumaronitrile-chromium(0),-molybdenum(0), and -tungsten(0)
Mour, Ïzzet A.; Özkar, Saim; Kreiter, Cornelius G. (1994-08-01)
Photolysis of hexacarbonyl-chromium(0), -molybdenum(0), and -tungsten(0) in presence of fumaronitrile yields at room tem perature pentacarbonyl-fumaronitrile-chromium(0)(1), -molybdenum(0) (2), and -tungsten(O) (3). The complexes were purified by crystallization and characterized by IR and 13C-NMR spectroscopy. The fumaronitrile ligand is bonded to the M(CO)5 moiety by one nitrile nitrogen atom rather than by the carbon-carbon double bond. In toluene 2 dissociates into fumaronitrile and pentacarbonyl-molybd...
SYNTHESIS AND SPECTROSCOPIC STUDIES OF PENTACARBONYLFUMARONITRILE-CHROMIUM(0), PENTACARBONYLFUMARONITRILE-MOLYBDENUM(0), AND PENTACARBONYLFUMARONITRILE-TUNGSTEN(0)
MOUR, IA; Özkar, Saim; KREITER, CG (1994-08-01)
Photolysis of hexacarbonyl-chromium(0), -molybdenum(0), and -tungsten(0) in presence of fumaronitrile yields at room temperature pentacarbonyl-fumaronitrile-chromium(0) (1): molybdenum(0) (2), and -tungsten(0) (3). The complexes were purified by crystallization and characterized by IR and C-13-NMR spectroscopy. The fumaronitrile ligand is bonded to the M(CO)(5) moiety by one nitrile nitrogen atom rather than by the carbon-carbon double bond. In toluene 2 dissociates into fumaronitrile and pentacarbonyl-moly...
Synthesis of benzimidazole containing donor acceptor electrochromic polymers
Akpınar, Hava Zekiye; Toppare, Levent Kamil; Department of Chemistry (2011)
Donor-acceptor-donor (DAD) type benzimidazole (BIm) and 3,4-ethylenedioxythiophene (EDOT) bearing monomers (4-(2,3-Dihydrothieno[3,4-b][1,4]dioxin-5-yl)-7-(2,3 dihydrothieno[3,4b][1,4] dioxin-7-yl)-2-benzyl-1H-benzo[d]imidazole (M1), 2,4-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-7-(2,3-dihydrothieno[3,4-b][1,4]dioxin-7-yl)-1H-benzo[d]imidazole (M2) and 4-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-7-(2,3-dihydrothieno[3,4-b][1,4]dioxin-7-yl)-2-ferrocenyl-1H-benzo[d]imidazole (M3)) were synthesized and el...
Synthesis and Characterization of Conducting Copolymers of Quinoxaline Derivatives
Turac, Ersen; Sahmetlioglu, Ertugrul; Toppare, Levent Kamil; Yuruk, Huseyin (Wiley, 2011-05-05)
Electrochemical copolymerizations of 2,3-di(2-thienyl)quinoxaline (M1), 6-methyl-2,3-di(2-thienyl)quinoxaline (M2), and 2,3-di(2-thienyl)quinoxaline-6-yl)(phenyl)methanone (M3) with 3,4-ethylenedioxy thiophene (EDOT) were carried out in CH3CN/TBABF(4) (0.1M) solvent-electrolyte couple via potentiodynamic electrolysis. The obtained copolymers were characterized by cyclic voltammetry (CV), Fourier transform-infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and thermogravimetry analyses (TGA). ...
Mechanism of aggregation control by detergent and dispersants: a multiscale modeling study
Özdemir, Erhan; Kan, Esra; Guo, Binbin; Ağıral, Anıl; Yıldırım, Erol (2022-10-07)
Insoluble nanopartecles formed dureng the combusteon en the passenger car engenes leads to the formateon of deposets en both lubrecant oel and engene pestons. These sludge and sooth type partecles bueld-up and deposet on the surfaces of engene en teme, whech damages the engene due to the abraseve nature of them. Detergents and despersants are the major addeteves en lubrecant formulateons to prevent thes aggregateon and decrease deposet formateons.
