The structure of the title compound, C8H12O2, which is a rearrangement product of the reaction of 6-hydroxy-4,4-dimethylcyclohex-2-en-1-one and 4-dimethylaminopyridine has been identified as 2-hydroxy-5,5-dimethylcyclohex-2-en-1-one, The C atom of the six-membered ring connected to the two methyl groups is 0.617(2)Angstrom out of the least-squares plane defined by the other C atoms of the rin. The unit cell consists of discrete molecules with intra-and intermolecular hydrogen bonds.


Synthesis and spectroscopic characterization of group 6 pentacarbonyl(4-substituted pyridine)metal(0) complexes
Tuc, Cigdem; Morkan, Izzet Amour; Özkar, Saim (2007-09-01)
Carbonyl-metal (M:Cr, Mo, W) derivatives of 4-substituted pyridines [4-methylpyridine (4-mp), 4-tert-butylpyridine (4-tbp) and 4-dimethylaminopyridine (4-dmap)] where the metal center is bonded to the nitrogen atom of the substituted pyridine ring are described. The organometallic complexes, M(CO)(5)L, were synthesized by either the direct reaction of the metal hexacarbonyls or by the thermal substitution of M(CO)(5)(THF) with the pyridine ligands; 4-methylpyridine (1), 4-tert-butylpyridine (2), 4-dimethyla...
1-Aryl-3,5-dimethylpyrazolium based tunable protic ionic liquids (TPILs)
Özdemir, Melek; AKTAN, EBRU (2019-03-15)
A series of new 1-aryl-3,5-dimethylpyrazolium based tunable protic ionic liquids/salts ([Ph(R)Hpz][X], R: -H, -Cl, -Br, -CH3, -OCH3, X: chloride [Cl-] and tetrafluoroborate (BF4-) have been synthesized through acid-base neutralization reactions between 1-aryl-3,5-dimethy1-1H-pyrazoles and the corresponding inorganic acids. The chemical structure of the salts was confirmed by FTIR, H-1 NMR, C-13 NMR, elemental analysis, and F-19 NMR (3a-3e) and the crystal structure of the two salts (2a and 3d) was also eluc...

Peptidotriazolamers are hybrid foldamers combining features of peptides and triazolamers-repetitive peptidomimetic structures with triazoles replacing peptide bonds. We report on the synthesis of a new class of peptidomimetics, containing 1,5-disubstituted 1,2,3-triazoles in an alternating fashion with amide bonds and the analysis of their conformation in solid state and solution. Homo-or heterochiral peptidotriazolamers were obtained from enantiomerically pure propargylamines with stereogenic centers in th...

Ulku, D; Tahir, MN; Demir, Ayhan Sıtkı; Aksoy-Cam, H (1998-01-15)
In the title compound, C8H9NO4, the hydrogen bonds between the oxime O atoms and the N and O atoms of the neighbouring asymmetric unit result in the dimerization of the molecules, with D...A distances of 2.774 (3) and 3.144 (3) Angstrom for O-H ... N and O-H ... O, respectively. The hydrogen-bridged centrosymmetric dimers are cross-linked via additional weaker intermolecular hydrogen bonds between the CH3 group and the other O atom of the dimer, forming a polymeric network. The D...A distance of this second...
Conducting polymers of decanedioic acid bis-(4-pyrrol-1-yl-phenyl) ester
Çırpan, Ali; Toppare, Levent Kamil (Elsevier BV, 2004-05-15)
A dipyrrolyl monomer was synthesized via the reaction between 4-pyrrol-1-yl phenol and decanedioyl dichloride. The electrochemical behavior of this monomer was studied. Polymerization of decanedioic acid bis-(4-pyrrol-1-yi-phenyl) ester (DAPE) was achieved by chemical and constant current electrolyses methods. Copolymerization of DAPE with thiophene was performed by constant potential electrolysis in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB), dichloromethane-TBAFB, solvent-electrolyte couple...
