Cuboidal Mo3S4 Clusters as a Platform for Exploring Catalysis: A Three-Center Sulfur Mechanism for Alkyne Semihydrogenation
(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 ...
Photogeneration of Hydrogen from Water by Hybrid Molybdenum Sulfide Clusters Immobilized on Titania
(John Wiley & Sons, 2015)
Two new hybrid molybdenum(IV) Mo3S7 cluster complexes derivatized with diimino ligands have been prepared by replacement of the two bromine atoms of [Mo3S7Br6]2− by a substituted bipyridine ligand to afford heteroleptic ...
Synthesis, Structure, Gas-Phase Reactivity, and Catalytic Relevance of Trinuclear Mo3S4 Clusters Bearing Terminal Hydroxo and Hydrosulfido Groups
(WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2013-11)
Molybdenum(IV) hydroxo [Mo3S4(dmpe)3(OH)3]+ (1+) and hydrosulfido [Mo3S4(dmpe)3(SH)3]+ (2+) [dmpe = 1,2-bis(dimethylphosphanyl)ethane] trimetallic cuboidal cluster complexes have been isolated in high yields by treating ...
Unsymmetrically Substituted Mo3S44+ Clusters Bearing Diphosphane Ligands
(WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2013-03)
A unique series of unsymmetrically substituted [Mo3S4(dmpe)3Cl3–x(dca)x]PF6 (x = 0–3) clusters that feature mixed Cl/dca terminal ligands, prepared by thermal reaction of [Mo3S4(dmpe)3Cl3]PF6 ([1]PF6) [dmpe = 1,2-bis(dim ...
Use of a cubane-type Mo3 CoS4 molecular cluster as paramagnetic unit in the synthesis of hybrid charge-transfer salts
(Elsevier, 2010)
Selective substitution of the chlorine atom coordinated to cobalt in the paramagnetic Mo<sub>3</sub>(CoCl)S<sub>4</sub>(dmpe)<sub>3</sub>Cl<sub>3</sub> (dmpe = 1,2-bis(dimethylphosphanyl) ethane) complex with a S = 1/2 ...
Mechanism of the catalytic gas-phase aldehyde production from trinuclear W3S4 complexes bearing W-OEt groups
(Elsevier, 2011)
Collision induced dissociation experiments of the alkoxo [W3S4(dmpe)2(O)(OCH2CH3)]+ tungsten (IV) cation reveal that aldehyde elimination is the dominant reaction pathway. Complementary deuterium labelling experiments give ...
Unprecedented Solvent-Assisted Reactivity of Hydrido W3CuS4 Cubane Clusters: The Non-Innocent Behaviour of the Cluster-Core Unit
(Wiley, 2009)
Opening the cluster core: Substitution of the chloride ligand in the novel cationic cluster [W3CuS4H3Cl(dmpe)3]+ (see figure; dmpe=1,2-bis(dimethylphosphino)ethane) by acetonitrile is promoted by water addition. Kinetic ...
Promiscuity in alkaline phosphatase superfamily: unraveling evolution through molecular simulations
(American Chemical Society, 2011-08)
We here present a theoretical study of the alkaline hydrolysis of a phosphodiester (methyl p-nitrophenyl phosphate or MpNPP) in the active site of Escherichia coli alkaline phosphatase (AP), a monoesterase that also presents ...
Molecular mechanism of chorismate mutase activity of promiscuos MbtI
(Springer, 2010-06-15)
Salicylate synthase from Mycobacterium tuberculosis, MbtI, initiates the biosynthesis of siderophores by converting chorismate to salicylate. Nevertheless, three more distinct activities for wild-type MbtI have been detected ...
"Eppur si muove" (yet it moves)
(National Academy of Sciences, 2011-09-13)
In the 17th century, the problem of the relative movement of the Earth with respect to the sun was an issue of central importance, and in fact, the man who has been considered responsible for the birth of modern science ...
