A tricyclic ring system of six carbon and five boron atoms from monoalkylbenzene and five formal borene units
Products of RC6H,*5BNR‘, are the highest borylated species to be formed in reactions between dehalogenation products of F,BN(i-Pr), with monoalkylbenzenes.The structures are cages, each consisting of a five-, six-, and ...
Comparison of the X-ray crystal structures of the sodium and potassium 2,4,6-tris(trifluoromethyl)phenoxides (RO–) and 2,4,6-tris(trifluoromethyl)benzenethiolates (RS–); [Na(OR)(thf)2]2, [K(OR)(thf)2(µ-thf)]2, [Na(SR)(thf)2·0.25thf]x and [K(SR)(thf)]x(thf = tetrahydrofuran)
Na(OR)(thf)2]21, [K(OR)(thf)2(µ-thf)]22, [Na(SR)(thf)2·0.25thf]x3 and [K(SR)-(thf)]x4 were formed by the reaction of the appropriate combinations of 2,4,6-tris(trifluoromethyl)phenol (ROH) or 2,4,6-tris(trifluorornethyl) ...
Struktur von [CPRu(C0)2]2 (Cp = η5-pentamethylcyclopentadienyl)
The molecular structure of di-μ-carbonyl-bis[carbonyl(η5-pentamethylcyclopentadienyl)ruthenium] (Ru---Ru) has been determined by a single-crystal X-ray diffraction study (monoclinic, space group P21/n,a = 979.90(9), b = ...
Synthesen und Strukturen von cyclischen und acyclischen Vanadium(V)- und Molbydän(VI)-haltigen Verbindungen
The reaction of (C2F5)2P(Cl)NSiMe3 (2) with Cl3VNSiMe3 in CH2Cl2 yields the eight-membered ring [(C2F5)2PN2VCl2]2 (3). (CF3)2P(Cl)NSiMe3 (1) reacts with VOCl3 to form the eight-membered ring [(CF3)2PN]3NVCl2 (4). A ...
A biomimetic domino reaction for the concise synthesis of capreomycidine and epicapreomycidine
(Springer Vienna, 2012)
The non-proteinogenic amino acids capreomycidine and epicapreomycidine are constituents of antibiotically active natural products, but the synthesis of these unusual cyclic guanidine derivatives is challenging. The ...
Lipid reorganization induced by Shiga toxin clustering on planar membranes.
The homopentameric B-subunit of bacterial protein Shiga toxin (STxB) binds to the glycolipid Gb(3) in plasma membranes, which is the initial step for entering cells by a clathrin-independent mechanism. It has been suggested ...
Multiblock Copolymers of Styrene and Butyl Acrylate via Polytrithiocarbonate-Mediated RAFT Polymerization
When linear polytrithiocarbonates as Reversible Addition-Fragmentation chain Transfer (RAFT) agents are employed in a radical polymerization, the resulting macromolecules consist of several homogeneous polymer blocks, ...
Structure solution of DNA-binding proteins and complexes with ARCIMBOLDO libraries.
Protein-DNA interactions play a major role in all aspects of genetic activity within an organism, such as transcription, packaging, rearrangement, replication and repair. The molecular detail of protein-DNA interactions ...
On the temperature dependence of H-U iso in the riding hydrogen model
The temperature dependence of H-Uiso in N-acetyl-l-4-hydroxyproline monohydrate is investigated. Imposing a constant temperature-independent multiplier of 1.2 or 1.5 for the riding hydrogen model is found to be inaccurate, ...
Final rotational state distributions from NO(vi = 11) in collisions with Au(111): the magnitude of vibrational energy transfer depends on orientation in molecule-surface collisions.
When NO molecules collide at a Au(111) surface, their interaction is controlled by several factors; especially important are the molecules' orientation with respect to the surface (N-first vs. O-first) and their distance ...
