In: Chemistry - A European Journal, 2006, vol. 13, no. 1, p. 292-299

The dinuclear cation [(C6Me6)2Ru2 (PPh2)H2]+ (1) has been studied as the catalyst for the hydrogenation of carbon-carbon double and triple bonds. In particular, [1][BF4] turned out to be a highly selective hydrogenation catalyst for olefin functions in molecules also containing reducible carbonyl...

Nondestructive Room-Temperature Adsorption of 2,4,6-tri(2t-thienyl)-1,3,5-triazine on a Si-B Interface: High-Resolution STM Imaging and Molecular Modeling

Makoudi, Y. ; Palmino, F. ; Duverger, E. ; Arab, M. ; Chérioux, Frédéric ; Ramseyer, C. ; Therrien, Bruno ; Tschan, Mathieu J.-L. ; Süss-Fink, Georg

In: Physical Review Letters, 2008, vol. 100, no. 076405, p. 1-4

Organic nanostructures on semiconductors are currently investigated but the surfaces are known to interact strongly with molecules. To reduce the molecule-surface interaction, we used the Si(111)-B √3 × √3R30°. Deposition of isolated 2,4,6-tri(2t-thienyl)-1,3,5-triazine, was achieved at room temperature without modification of their π skeleton. This fascinating...

Supramolecular cluster catalysis : facts and problems

Süss-Fink, Georg ; Therrien, Bruno ; Vieille-Petit, Ludovic ; Tschan, Mathieu J.-L. ; Romakh, Vladimir B. ; Ward, Thomas R. ; Dadras, Massoud ; Laurenczy, Gabor

In: Journal of Organometallic Chemistry, 2004, vol. 689, p. 1362-1369

By checking the chemistry underlying the concept of "supramolecular cluster catalysis" we identified two major errors in our publications related to this topic, which are essentially due to contamination problems. (1) The conversion of the "closed" cluster cation [H3Ru3(C6H6)(C6Me6)2(O)]+ (1) into the...
