Linear alkylbenzenes (LABs) comprising >80% 2-phenyl isomer content, have been prepared in sustainable high yields from detergent-range linear olefins via regioselective benzene alkylation using reactive distillation technology. Hydrofluoric acid (HF)-treated mordenites provide enhanced, shape-selective, ...

THE present invention relates to the separation of two isomers, CHARACTERIZED (I) BECAUSE selectively CONDENSA ONE OF THEM WITH A PRODUCT THAT HAS AT LEAST ONE allylic hydrogen in the presence of Friedel-Crafts, (II) and then The condensation product obtained is the other isomer. In a mixture...
This suggestion can partly explain the similarities of a pair of xanthones: norathyriol (8) and its isomer 1,3,5,6-tetrahydroxyxanthone (9). As shown in Table 1, in PTIO•-trapping colorimetric analysis, there is no significant difference (p > 0.05) in IC50 values at pH 4.5 between ...
23Citations Metrics Abstract In this present work, we theoretically investigate the excited state mechanism for the 2-(phenyl)imidazo[4,5-c]pyridine (PIP-C) molecule combined with methanol (MeOH) solvent molecules. Three MeOH molecules should be connected with PIP-C forming stable PIP-C-MeOH...

The absolute configuration at both chiral centres of the diastereoisomer is S. The (S)s absolute configuration at the sulphur atom has been correlated with the negative Cotton effect assigned to a charge-trasfer transition at 265 nm in the circular dichroism spectrum. The diastereoselective ...
