Making C-C bond with gold catalysts: A theoretical study of the influence of gold particle size on the dissociation of the C-X bond in aryl halides

Boronat Zaragoza, Mercedes; López Auséns, Javier Tirso; Corma Canós, Avelino (American Chemical Society, 2014-05-01)

The adsorption and activation of iodo-, bromo-, and chlorobenzene over gold catalysts of different size, including an extended Au(111) surface; three-dimensional Au38 and Au13 nanoparticles; and planar Au7, Au6, and Au3 ...
Pd embedded in chitosan microspheres as tunable soft-materials for Sonogashira cross-coupling in water-ethanol mixture

Frindy, Sana; Primo Arnau, Ana María; Lahcini, Mohamed; Bousmina, Mosto; García Gómez, Hermenegildo; El Kadib, Abdelkrim (Royal Society of Chemistry, 2015)

Easy shaping of chitosan (CS) as porous self-standing nanofibrillar microspheres allows their use as a palladium carrier. Amino-groups on CS enable the modulation of Pd coordination, giving rise to three different ...
Well-Defined Noble Metal Single Sites in Zeolites as an Alternative to Catalysis by Insoluble Metal Salts

Rubio Marqués, Paula; Rivero Crespo, Miguel Ángel; Leyva Perez, Antonio; Corma Canós, Avelino (American Chemical Society, 2015-09-16)

Insoluble precious metal chlorides in polymeric form (i.e., PtCl2, PdCl2, AuCl, RhCl3) are commonly used as catalysts for a plethora of organic reactions in solution. Here we show that only the minor soluble fraction of ...
