Methyl 4′,5-dichloro-2-hydroxy-4,6-dimethylbiphenyl-3-carboxylate
In the title compound, C(16)H(14)Cl(2)O(3), the dihedral angle between the mean planes of the two benzene rings is 55.30 (5)°. The methyl ester group lies within the ring plane due to an intra-molecular O-H⋯O hydrogen bond [maximum deviation from the C(8)O(2) mean plane is 0.0383 (13) Å]. In the crystal, mol-ecules are held together by rather weak C-H⋯O hydrogen bonds.

In the crystal structure of the title compound, C(19)H(17)Cl(2)NO, the indoline and benzopyran ring systems are approximately perpendicular to each other. The indoline ring is in an envelope conformation with the spiro C atom as the flap. The N atom of the indoline ring forms a pyramidal environment, the sum of the angles at this atom being 352.46°.
متن کاملSpectroscopic studies on the interaction of cilostazole with iodine and 2,3-dichloro-5,6-dicyanobenzoquinone.
The electron accepting properties of the 2,3-dichloro-5,6-dicyanobenzoquinone and iodine and electron donating properties of the drug cilostazole have been studied using the UV-vis, FT-IR, GC-MS and Far-IR techniques. The interaction of cilostazole drug with iodine and 2,3-dichloro-5,6-dicyanobenzoquinone resulted via the initial formation of charge-transfer complex as an intermediate. The rate...
متن کاملA facile and high efficient synthesis of nitriles from aldoximes and primary amides with a mixture of triphenylphosphine/2, 3-dichloro-5, 6- dicyanobenzoquinone (PPh3/DDQ) under neutral conditions
Several methods have been reported for preparation of nitriles by dehydration of aldoximes using selenium dioxide-chloroform, diphosphorus tetraiodide, trifluoroacetic anhydride-pyridine, chlorosulphonyl isocyanate, 4,6-dipheny-2-methylthio-pyriliumtetrafluoro borate, copper (II) acetate-acetonitrile, trichloroacetyl chloride-triethylamine, triphenylphosphine/carbontetrachloride (PPh3/CCl4) in ...
