3,5-Dibromo-2-aminobenzamide was reacted with 1,3-cyclohexanedione derivatives in the presence of iodine as catalyst in toluene under reflux to afford novel 6,8-dibromo-2-[3-(2´-alkyl-1´,2´,3´,4´-tetrahydro-6´,8´-dibromo ...

103Pd is an important therapeutic radionuclide and has recently found great interest due to its higher radiobiologic effect. 109Cd decays by electron capture and is generally used as calibration sources in industrial and ...

The distribution and potential sources of 15 polycyclic aromatic hydrocarbons (PAHs) in soils and Digitaria eriantha in the vicinity of three South African coal-fired power plants, Matla, Lethabo and Rooiwal were determined ...

Highly selective and sensitive phosphate sensors have been fabricated by constructing a solid membrane disk consisting of variable mixtures of aluminium powder (Al), aluminium phosphate (AlPO4) and powdered copper (Cu). ...

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 ...

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 ...

The syntheses of aromatic oxazolyl functionalized chain end polystyrene and poly(methyl methacrylate) using an oxazolyl functionalized initiator in atom transfer radical polymerization were effected by the following ...

Sonogashira cross-coupling of 2-aryl-4-chloro-3-iodoquinoline derivatives with stoichiometric amount of terminal alkynes in the presence of bis(triphenylphosphine)palladium(II)chloride and copper iodide in triethylamine ...

The use of magnesium hydroxide (Mg(OH)2) as a flame retardant and smoke-suppressor in polymeric materials has been of great interest recently. Because it contains no halogens or heavy metals, it is more environmentally ...

The main objective of this investigation was to study palladium-catalyzed coupling of 2-aryl-4-chloro-3-iodoquinolines with phenyl boronic acid in order to assess the regioselectivity of carbon-carbon bond formation at ...
