15 de jul. de 2019 · Gold nanorings are attractive as plasmonic metal nanocrystals because they have a hollow inner cavity. Their enhanced electric field inside the ring cavity is accessible, which is highly desirable for assembling with other optical components and studying their plasmon-coupling behaviors.
16 de abr. de 2023 · Herein, we report a gold-catalyzed Heck reaction facilitated by the ligand-enabled Au(I)/Au(III) redox catalysis. The elementary organometallic steps such as migratory insertion and β-hydride elimination have been realized in the catalytic fashion for the first time in gold chemistry. The present methodology not only overcomes the limitations of previously known transition metal-catalyzed ...
The first report on gold-catalyzed cross-coupling reactions describes the reaction of aryl halides 3a with electron-rich arenes 3b by utilizing MeDalPhos ligand. 10 As per DFT studies, ...
24 de may. de 2019 · The red shift of the absorption wavelength originates from the combination of [Au 2 (μ-dppm) 2 ]Cl 2 and ligand (Ph 3 P or mercaptan). On the basis of this finding, a gold-catalyzed reductive desulfurizing C–C coupling of electrophilic radicals and styrenes mediated by blue LEDs is presented, a coupling which cannot be efficiently accessed ...
15 de ene. de 2010 · 319; see the Perspective by Christensen and Nørskov) created high–surface area gold catalysts by leaching silver from gold-silver alloys. This material proved to be an effective catalyst for partial oxidative coupling of methanol, yielding methyl formate.
13 de dic. de 2023 · While promoting direct C-C coupling using EAO mediated gold redox chemistry is interesting, arguably, the most unique reactivity of cationic gold catalysis over other metal cations is the ...
