Electrooxidation of Ammonia at Tuned (100)Pt Surfaces by using Epitaxial Thin Films
Authors: Galipaud Jules , Roy Claudie , Martin Manuel H. , Garbarino Sébastien , Roué Lionel , Guay Daniel 
Published: April 2015

AbstractPtxNi100−x thin films (72≤x≤100, 10–25 nm thick) were deposited on MgO (100) substrates by using pulsed laser deposition. As shown from X‐ray diffraction analysis, the formation of a Pt(Ni) solid solution was observed over the Ni range investigated. All PtNi‐based films showed epitaxial growth in the (100) direction at 350 °C, which is in contrast to pure Pt films, where a Ni seeding layer was required to obtain epitaxial deposits at this temperature. X‐ray photoelectron spectroscopy depth‐profile analyses showed a Ni enrichment at the PtNi/MgO interface, which may be at the origin of the epitaxial growth in the alloys. After immersion in acidic media, Ni atoms are totally dissolved from the first ten atomic layers of the PtNi films, forming pure Pt electrodes. On the basis of underpotential‐deposited hydrogen electrochemical analyses, a (100) preferential surface orientation of the crystallites originating from epitaxial growth was confirmed on both Ptseeded and PtxNi100−x films. It was shown that the fraction of (100) terraces and terrace edge sites are a determining factor in the electrooxidation of NH3. The highest electrocatalytic activity was observed with the Ptseeded film.

Published: April 2015

AbstractIn this contribution, we report on novel functionalized triazines, which represent new precursors for C/N/(H) compounds or suitable building blocks for carbon‐based functional networks. Our results provide insights into the structural properties of molecular carbon nitride materials and their design principles. Tris(1‐propynyl)‐1,3,5‐triazine (C3N3(C3H3)3) and tris(1‐butynyl)‐1,3,5‐triazine (C3N3(C4H5)3) were prepared by substitution reactions of cyanuric chloride (C3N3Cl3) with prop‐1‐yne and but‐1‐yne. The crystal structure of tris(1‐propynyl)‐1,3,5‐triazine was solved in the orthorhombic space group Pbcn (Z=4, a=1500.06 (14), b=991.48(10), c=754.42(6) pm, V=1122.03(18)×106 pm3), whereas tris(1‐butynyl)‐1,3,5‐triazine crystallized in the triclinic space group P−1 (Z=6, a=1068.36(12), b=1208.68(12), c=1599.38(16) pm, α=86.67(3), β=86.890(4), γ=86.890(4)°, V=1997.7(4)×106 pm3). For both structures, planar triazine units and layerlike packing of the molecules were observed. Tris(1‐propynyl)‐1,3,5‐triazine is built up from hydrogen‐bonded zig‐zag strands, whereas tris(1‐butynyl)‐1,3,5‐triazine shows parallel layered arrangements. Both compounds were investigated by NMR spectroscopy, IR spectroscopy, and differential thermal analysis/thermogravimetric analysis, which provided insights into their structural, chemical, and thermal properties. In addition, tris(1‐propynyl)‐1,3,5‐triazine was pyrolyzed and a new polymeric triazine‐based compound containing mesitylene units was obtained. Its structural features and properties are discussed in detail.
Design and Stereoselective Synthesis of ProM‐2: A Spirocyclic Diproline Mimetic with Polyproline Type II (PPII) Helix Conformation

Published: April 2015

AbstractWith the aim of developing polyproline type II helix (PPII) secondary‐structure mimetics for the modulation of prolin‐rich‐mediated protein–protein interactions, the novel diproline mimetic ProM‐2 was designed by bridging the two pyrrolidine rings of a diproline (Pro–Pro) unit through a Z‐vinylidene moiety. This scaffold, which closely resembles a section of a PPII helix, was then stereoselectively synthesized by exploiting a ruthenium‐catalyzed ring‐closing metathesis (RCM) as a late key step. The required vinylproline building blocks, that is, (R)‐N‐Boc‐2‐vinylproline (Boc=tert‐butyloxycarbonyl) and (S,S)‐5‐vinylproline‐tert‐butyl ester, were prepared on a gram scale as pure stereoisomers. The difficult peptide coupling of the sterically demanding building blocks was achieved in good yield and without epimerization by using 2‐(1H‐7‐azabenzotriazol‐1‐yl)‐1,1,3,3‐tetramethyluronium hexafluorophosphate (HATU)/N,N‐diisopropylethylamine (DIPEA). The RCM proceeded smoothly in the presence of the Grubbs II catalyst. Stereostructural assignments for several intermediates were secured by X‐ray crystallography. As a proof of concept, it was shown that certain peptides containing ProM‐2 exhibited improved (canonical) binding towards the Ena/VASP homology 1 (EVH1) domain as a relevant protein interaction target.

Published: April 2015

AbstractA novel octacobalt‐containing polyoxoniobate, Na6K12[H2Co8O4(Nb6O19)4]⋅39 H2O, has been prepared by a combination of hydrothermal and diffusion methods. The polyanion [H2Co8O4(Nb6O19)4]18− incorporates a tetrameric assembly of Lindqvist‐type [Nb6O19]8− fragments trapping a {CoII4CoIII4} cluster which comprises a central {CoIII4O4} cubane core, surrounded by another four CoII ions linkers. Furthermore, magnetic measurements show that the compound exhibits antiferromagnetic interactions.

Published: April 2015

AbstractTwo attractive chirons, aldehyde 6 and chloride 7, exhibiting functionalized ent‐spongiane‐type tricyclic skeletons (ABC ring system), have been constructed and their absolute configurations have been studied by NMR spectroscopy and confirmed by single‐crystal X‐ray diffraction. Both of these chirons are derived from commercially available andrographolide in good yield. Aldehyde 6 is obtained through a novel K2S2O8‐catalyzed aquatic ring‐closing reaction of allylic sodium sulfonate and intramolecular 1,7‐hydrogen atom transfer process. Further mechanistic investigations demonstrate that the 1,7‐hydrogen atom transfer is a free‐radical process, whereby hydrogen migrates from C18 to C17, as evidenced by double‐18‐ deuterium‐labeled isotope experiments. Prospective applications of these two chiral sources are also discussed.

The radical‐based methodology presented here allows to access highly‐functionalized trifluoromethyl arenes in up to 81 % chemical yield.
Enantioselective Synthesis of Tertiary Propargylic Alcohols under N‐Heterocyclic Carbene Catalysis

Published: April 2015

AbstractA straightforward procedure to carry out the enantioselective benzoin reaction between aldehydes and ynones by employing a chiral N‐heterocyclic carbene (NHC) as catalyst was developed. Under the optimized reaction conditions, these ynones undergo a clean and selective 1,2‐addition with the catalytically generated Breslow intermediate, not observing any byproduct arising from competitive Stetter‐type reactivity. This procedure allows the preparation of tertiary alkynyl carbinols as highly enantioenriched materials, which have the remarkable potential to be used as chiral building blocks in organic synthesis.
