Thermal Hydrocracking of 2, 4, 6-Trimethylphenol

Structural , Spectroscopic Investigation and Quantum Chemical Calculation Studies of 2 , 4 , 6 - trimethylphenol for Pharmaceutical Application

The FTIR and FT-Raman spectra of 2,4,6-trimethylphenol (TMP) have been recorded in the regions 4000-400 cm and 3500-50 cm, respectively. The optimum molecular geometry, harmonic vibrational frequencies, infrared intensities and Raman scattering activities were calculated by ab initio Hartree–Fock (HF) and density functional theory (DFT/B3LYP) methods using 6-31+G(d,p) basis set. The normal mode...

Synthesis and Biological Evaluation of 4-hydroxychromenyl arylmethyl-6-hydroxy pyrimidine-2, 4-dione Derivatives

Background: An efficient, promoted tri-component catalytic reaction between barbituric acid (or N,N-dimethyl barbituric acid), 4-hydroxy coumarin, and a wide range of aryl aldehydes using zinc oxide nanowires (ZnO NWs) to obtain some new 4-hydroxychromenylarylmethyl-6-hydroxypyrimidine-2,4-diones is described. Method: The reactants were successfully condensed ...

SYNTHESIS OF 8-HYDROXY-6-METHOXY- 3-UNDECYLISOCOUMARIN AND 2-HY DROXY - 4-METHOXY-6-(2-OXOTRIDECYL) BENZOIC ACID

Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...

6-Chloro-2-(4-meth­oxy­phen­yl)-4-phenyl­quinoline

In the title compound, C22H16ClNO, the quinoline ring system makes dihedral angles of 56.30 (6) and 7.93 (6)°, respectively, with the adjacent phenyl and benzene rings. The dihedral angle between these phenyl and benzene rings is 56.97 (8)°. In the crystal, weak C-H⋯π and π-π [centroid-centroid distances of 3.7699 (9) and 3.8390 (9) Å] inter-actions link the mol-ecules into a layer parallel to ...
