[EN] The generation of a carbocation with an acid depends not only on the acid strength but also on the ability of the counteranion to stabilize the positive charge left behind. Here we report that despite their relatively ...

[EN] N-Alkylamines are key intermediates in the synthesis of fine chemicals, dyes, and natural products, and hence are highly valuable building blocks in organic chemistry. Consequently, the development of greener and more ...

[ES] En el presente trabajo final de máster se ha desarrollado por primera vez una metodología sintética para la hidrodesoxigenación selectiva de imidas N-heterocíclicas a las correspondientes lactamas. Para llevar a ...

[EN] A heterogeneously catalyzed protocol for the acceptorless dehydrogenative condensation between N,N'-disubstituted ureas and 1,2-diols to afford imidazolones was developed. Palladium nanoaggregates stabilized onto an ...

[EN] In this work it is shown that iron(III) and gold(I) triflimide efficiently catalyze the hydroaddition of a wide array of nucleophiles including water, alcohols, thiols, amines, alkynes, and alkenes to multiple CC ...

[ES] La presente tesis doctoral se basa en la síntesis, caracterización y uso de catalizadores basados en especies de Pd soportadas sobre matrices sólidas en reacciones de interés en química fina. En general, se ha pretendido ...

[EN] Kinetic analysis of ruthenium-catalyzed reductive N-methylation of amines using dimethyl carbonate as C1 source and molecular hydrogen as reductant has been performed. Kinetic equations have been derived and kinetic ...

[EN] An efficient heterogeneous silver-catalyzed ¿-alkylation of nitriles and oxindoles using alcohols via borrowing hydrogen strategy has been developed for the first time. The active nanostructured material, namely ...

Small gold nanoclusters in a very narrow size distribution (1.1 ( 0.5 nm) have been stabilized onto multiwalled carbon nanotubes (MWCNT). Theoretical studies supported by XPS and 16O2 / 18O2 isotopic exchange experiments ...

Aryl ketones substituted in ortho, meta, and para position are prepared by a palladium-catalyzed Sonogashira reaction followed by a regioselective hydration of the soformed alkyne with triflimidic acid or a gold catalyst, ...
