Base-Free Catalytic Hydrogen Production from Formic Acid Mediated by a Cubane-Type Mo3S4 Cluster Hydride
Guillamón, Eva; Sorribes, Iván; Safont Villarreal, Vicent Sixte; Algarra, Andrés G.; Fernández-Trujillo, M. Jesús; Pedrajas Gual, Elena; Llusar, Rosa; García Basallote, Manuel American Chemical Society (2022-10-14)Formic acid (FA) dehydrogenation is an attractive process in the implementation of a hydrogen economy. To make this process greener and less costly, the interest nowadays is moving toward non-noble metal catalysts and ... -
Benchmarking of DFTmethods using experimental free energies and volumes of activation for the cycloaddition of alkynes to cuboidalMo(3)S(4)clusters
Pedrajas Gual, Elena; Pino Chamorro, Jose Angel; Ferrer, Montserrat; Fernández-Trujillo, M. Jesús; Llusar, Rosa; Martínez, Manuel; García Basallote, Manuel; Algarra, Andrés G. Wiley (2020-06-25)Here, the kinetics of the concerted [3 + 2] cycloaddition reaction between the [Mo3(μ3‐S)(μ‐S)3Cl3(dmen)3]+ (dmen = N,N′‐dimethyl‐ethylenediamine) ([1]+) cluster and various alkynes to form dithiolene derivatives is ... -
Bifunctional W/NH Cuboidal Aminophosphino W3S4 Cluster Hydrides: The Puzzling Behaviour behind the Hydridic-Protonic Interplay
Guillamón, Eva; Beltrán Álvarez, Tomás Francisco; Safont Villarreal, Vicent Sixte; Castillo, Carmen E.; Algarra, Andrés G.; Fernández-Trujillo, M. Jesús; Pedrajas Gual, Elena; Pino Chamorro, Jose Angel; García Basallote, Manuel; Llusar, Rosa Wiley (2021-09-22)The novel [W3S4H3(edpp)3]+ (edpp=(2-aminoethyl)diphenylphosphine) (1+) cluster hydride with an acidic −NH2 functionality has been synthetized and studied. Its crystal structure shows the characteristic incomplete W3S4 ... -
Catalytic Hydrogenation of Azobenzene in the Presence of a Cuboidal Mo3S4 Cluster via an Uncommon Sulfur-Based H2 Activation Mechanism
Guillamón, Eva; Oliva, Mónica; Andres, Juan; Llusar, Rosa; Pedrajas Gual, Elena; Safont Villarreal, Vicent Sixte; Algarra, Andrés G.; García Basallote, Manuel American Chemical Society (2021)Azobenzene hydrogenation is catalyzed under moderate conditions by a cuboidal Mo3(μ3-S)(μ-S)3 diamino complex via a cluster catalysis mechanism. Dihydrogen activation by the molecular [Mo3(μ3-S)(μ-S)3Cl3(dmen)3]+ cluster ... -
Chemoselective Hydrogenation of Nitroarenes Catalyzed by Molybdenum Sulphide Clusters
Pedrajas Gual, Elena; Sorribes, Iván; Gushchin, Artem L.; Laricheva, Yuliya A.; Junge, Henrik; Beller, matthias; Llusar, Rosa Wiley (2017-03-20)Herein, we describe an atom efficient and general protocol for the chemoselective hydrogenation of nitroarenes to anilines catalyzed by well-defined diimino and diamino cubane-type Mo3S4 clusters. The novel diimino ... -
Cuboidal Mo3S4 Clusters as a Platform for Exploring Catalysis: A Three-Center Sulfur Mechanism for Alkyne Semihydrogenation
Algarra, Andrés G.; Guillamón, Eva; Andres, Juan; Fernández-Trujillo, M. Jesús; Pedrajas Gual, Elena; Pino Chamorro, Jose Angel; Llusar, Rosa; García Basallote, Manuel American Chemical Society (2018-08-03)We report a trinuclear Mo3S4 diamino cluster that promotes the semihydrogenation of alkynes. Based on experimental and computational results, we propose an unprecedented mechanism in which only the three bridging sulfurs ... -
