2-Aryl-6,8-Dibromo-4-Chloroquinazoline as scaffold for the synthesis of Novel 2,6,8-Triaryl-4-(Phenylethynyl)Quinazolines with potential photophysical properties

Paumo, Hugues Kamdem (2014-06)

The 2-aryl-6,8-dibromoquinazolin-4(3H)-ones were prepared in a single-pot operation by condensing 6,8-dibromoanthranilamide and aryl aldehydes in the presence of molecular iodine in ethanol. Treatment of the 2-aryl-6,8-d ...
2-ARYL-6,8-Dibromoquinolinones as synthons for the synthesis of Polysubstituted 4-ARYL-6-Oxopyrrolo [3,2,1-ij] Quinolines

Oyeyiola, Felix Adetunji (2015-09)

The known 2-aryl-6,8-dibromo-2,3-dihydroquinolin-4(1H)-ones 122 were dehydrogenated using thallium(III) p-tolylsulfonate in dimethoxyethane under reflux to afford the 2-aryl-6,8-dibromoquinolin-4(1H)-ones 136. Palladium-catalyzed ...
The application of experimental design to investigate the solvent matrix effects observed during the Determination of Rhodium (Rh) in organic media by Graphite Furnace Atomic Absorption Spectrometry (GFAAS)

Baratta, Antonio (2010-11)

In an industrial application a GFAAS method for monitoring the Rh concentration in process streams is being used. Matrix effects are known to exist with the application of this technique; in fact, it was observed that ...
Organometallic compounds : intermediates in organic synthesis

McGillivray, G. (Pretoria : University of South Africa, 1972)

Originally presented as an inaugural lecture delivered on 11 June 1970 at the University of South Africa
Palladium-catalyzed heteroannulation of 2-ARYL- 3-IODO-4-(Phenylamino)quinolines and 4-(N,N-allylphenylamino)-2-ARYL-3-iodoquinolines

Lesenyeho, Lehlogonolo Godfrey (2010-09)

The previously described 2-aryl-4-chloro-3-iodoquinolines were prepared following literature procedure and in turn converted to the corresponding hitherto unknown 2-aryl-3-iodo-4-(phenylamino)quinoline derivatives using ...
Synthesis and transformation of the 2,6,8-triaryl-2,3-dihydroquinolin-4(1H)-ones

Oyeyiola, Felix Adetunji (2011-11)

The 2-aryl-2,3-dihydroquinolin-4(1H)-ones were prepared via acid-catalyzed cyclization of the corresponding 2-aminochalcones, which were in turn, prepared by base-promoted Claisen-Schmidt aldol condensation of 2-aminoacetophenone ...
Synthesis, characterization and anticancer studies of Osmium-cymene complexes with O,O'- and P,P'-chelators as well as monodentate N- and P-donar ligands

Tapala, Kgaugelo Cornelius (2017-08)

Seventeen novel osmium cymene complexes with O,O′- and P,P′-chelating ligands as well as N- and P-monodentate ligands are reported. The osmium cymene complexes were synthesised and characterised by spectroscopic techniques ...
