Synthesis, anti-tuberculosis activity and QSAR study of 2,4-diarylquinolines and analogous polycyclic derivatives [PDF]
The multicomponent syntheses of 2,4-di-aryl-quinolines and analogous polycyclic derivatives as anti-tuberculosis agents were described. They were prepared via Beyer and Friedländer methods under microwave irradiation in short reaction times and good ...

Gas Phase Structure and Reactivity of Doubly Charged Microhydrated Calcium(II)-Catechol Complexes Probed by Infrared Spectroscopy [PDF]
Doubly charged microhydrated adducts formed from catechol and calcium(II) were produced in the gas phase using electrospray ionization (ESI) appearing as the most important ions in the mass spectra recorded. The gas phase structures of [Ca(catechol)2(H2O)

Radical Fluoroalkylation Reactions [PDF]
Recent protocols and reactions for catalytic radical perfluoroalkylations will be described. The production of perfluoroalkyl radicals (RF = CnF2n+1, n ≥ 2), which effect both addition and substitution reactions on organic substrates, can be realized ...
