2,5-Dichloro-1,4-benzoquinone

Room temperature solution studies of complexation between o-chloranil and a series of anilines by spectrophotometric method.

S Bhattacharya et al.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 57(12), 2409-2416 (2002-01-05)

Electron donor-acceptor (EDA) complex formation between o-chloranil and a series of anilines has been studied in CCl4 medium. In all the cases, EDA complexes are formed instantaneously on mixing the donor and acceptor solutions. N,N-dimethylaniline and N,N-dimethyl-p-toluidine form stable EDA

Determination of vertical ionization potential of nitroso-benzoimidazothiazole using charge transfer interaction with a series of acceptors.

Tandrima Chaudhuri et al.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 204, 403-408 (2018-07-04)

This is the first report of UV-Vis spectral investigations of electron donor-acceptor complexes of bio active 3-Nitroso-2-phenylbenzo[d]imidazo[2,1-b]thiazole (BIT1) with chloranils, nitrobenzenes and fullerenes in DMSO medium. Well defined charge transfer (CT) absorption bands in the visible region have been sited.

The first structural study on a cyclic tricoordinate phosphorochloridite and a pentacoordinate phosphorane based on 1,2,3,5-protected myo-inositol--a new conformation of 1,3,2-dioxaphosphorinane ring.

K V P Pavan Kumar et al.

Carbohydrate research, 342(9), 1182-1188 (2007-03-24)

Treatment of the phosphoramidite [myo-C(6)H(6)-2-[OC(O)Ph]-1,3,5-(O(3)CH)-4,6-(O(2)P-NH-i-Pr)] with o-chloranil affords the first example of inositol-based pentacoordinate phosphorane [myo-C(6)H(6)-2-[OC(O)Ph]-1,3,5-(O(3)CH)-4,6-(O(2)P-NH-i-Pr)(1,2-O(2)C(6)Cl(4))] (9) (X-ray structure) with a trigonal bipyramidal geometry at phosphorus. The six-membered 1,3,2-dioxaphosphorinane ring with the inositol residue has an unusual boat conformation in

Degradation of cyanidin 3-glucoside by caffeic acid o-quinone. Determination of the stoichiometry and characterization of the degradation products.

F Kader et al.

Journal of agricultural and food chemistry, 47(11), 4625-4630 (1999-12-20)

Caffeic acid o-quinone (CQ) was prepared by oxidation of caffeic acid with o-chloranil in organic media. The reaction between the purified CQ and cyanidin 3-glucoside (Cy 3-glc, o-diphenolic anthocyanin) was monitored by HPLC, and quantitative analyses were performed to establish

Sublethal effects of tetrachloro-1,2-benzoquinone--a component in bleachery effluents from pulp mills--on vertebral quality and physiological parameters in fourhorn sculpin.

B E Bengtsson et al.

Ecotoxicology and environmental safety, 15(1), 62-71 (1988-02-01)

The effects of tetrachloro-1,2-benzoquinone (TCQ), a component in bleached kraft mill effluents (BKME), on vertebral and physiological parameters were investigated in juvenile fourhorn sculpin, Myoxocephalus quadricornis L. After about 4.5 months of exposure to 0.1 and 0.5 mg TCQ/liter in
