Oxidation of 4-methoxy-1-naphthol on promoted platinum catalysts

Author: Maphoru, MV ; Heveling, J ; Kesavan Pillai, Sreejarani Date: Jul 2017 Oxidative coupling of naphthols is a useful method for the formation of new carbon-carbon bonds in organic synthesis. In the presence of hydrogen peroxide, platinum supported on activated carbon catalyses this reaction. The outcome is influenced ... Read more
Oxidative coupling of 1-naphthols over noble and base metal catalysts

Author: Maphoru, MV ; Heveling, J ; Kesavan Pillai, Sreejarani Date: Jan 2014 Bismuth-promoted platinum catalysts were tested for the oxidative coupling of 2- and 4-substituted 1-naphthols at different temperatures and ambient pressure. The principal final products are the 3,3'-substituted 1,1'-binaphthalenylidene-4,4'-diones ... Read more
Solvent and temperature effects on the platinum-catalyzed oxidative coupling of 1-naphthols

Author: Maphoru, MV ; Heveling, J ; Kesavan Pillai, Sreejarani Date: Aug 2015 Using H(sub2)O(sub2) as the oxidant, 1-naphthols with electron-donating groups at the 2- and 4-positions couple oxidatively over a carbon-supported platinum catalyst to 3,3'-substituted 1,1'-binaphthalenylidene-4,4'-diones and 4,4'-substituted ...

Structure-activity relationships of carbon-supported platinum-bismuth and platinum-antimony oxidation catalysts

Author: Maphoru, MV ; Kesavan Pillai, Sreejarani ; Heveling, J Date: Apr 2017 Compositional and morphological studies on supported platinum are important for the improvement and expanded use of catalysts for oxidative coupling reactions. Nanocomposites consisting of 5% Pt supported on activated carbon and promoted with ... Read more
