Cr(i)Cl as well as Cr+ are stabilised between two cyclic alkyl amino carbenes
Cr(I)Cl is a very unstable species. The present work describes the stabilisation of Cr(I)Cl in the low coordinate environment of cyclic alkyl(amino) carbene ligands and its synthetic application to yield an unprecedented ...
A stable silicon(ii) monohydride
A stable silicon(II) monohydride is accomplished through a covalent shared interaction of the silylene lone-pair and a sp3-hybridized boron atom of the Lewis acidic BH3. Experimental charge density investigations reveal ...
Probing bistability in Fe II and Co II complexes with an unsymmetrically substituted quinonoid ligand
The generation of molecular platforms, the properties of which can be influenced by a variety of external perturbations, is an important goal in the field of functional molecular materials. We present here the synthesis of ...
β-Glutamine-mediated self-association of transmembrane β-peptides within lipid bilayers
Transmembrane b-peptide helices and their association in lipid membranes are still widely unexplored. We designed and synthesized transmembrane b-peptides harboring different numbers of D-b3-glutamine residues (hGln) by ...
Exploiting amphiphilicity: facile metal free access to thianthrenes and related sulphur heterocycles.
Benzodithioloimines are reacted with arynes or alkynes substituted with electron-withdrawing groups to afford the corresponding thianthrene or benzo[b][1,4]dithiine derivatives. The transformation takes place under mild ...
New Rimocidin/CE-108 Derivatives Obtained by a Crotonyl-CoA Carboxylase/Reductase Gene Disruption in Streptomyces diastaticus var. 108: Substrates for the Polyene Carboxamide Synthase PcsA.
The rimJ gene, which codes for a crotonyl-CoA carboxylase/reductase, lies within the biosynthetic gene cluster for two polyketides belonging to the polyene macrolide group (CE-108 and rimocidin) produced by Streptomyces ...
Structure of sulfamidase provides insight into the molecular pathology of mucopolysaccharidosis IIIA.
Mucopolysaccharidosis type IIIA (Sanfilippo A syndrome), a fatal childhood-onset neurodegenerative disease with mild facial, visceral and skeletal abnormalities, is caused by an inherited deficiency of the enzyme ...
Vibrational spectra and structures of SinC clusters (n = 3-8).
The effects of doping bare silicon clusters with carbon on their physical properties are of fundamental interest for the chemistry of the interstellar medium and the development of novel nanostructures in materials science. ...
Wasser als Ligand in lithiierten organischen Verbindungen: [LiCH(CN)2 · H2O · TMEDA]
Nicht der zweizänhnige Aminligand, sondern Wasser koordiniert an die Li-Kationen in [LiCH(CN)2. TMEDA] 1 (TEMEDA = Tetramethylethylendiamin), din für lithiierte organische Verbindungen sehr ungewöhnliches Strukturmerkmal. ...
Preparation and structural characterization of dioxane-coordinated alkali metal bis(trimethylsilyl)amides
Unsolvated RbN(SiMe3)z (1) and CsN(SiMe3)z (2) have been prepared from rubidium and cesium metal respectively and excess hexamethyldisilazane. The molecular structures of the polymeric dioxane adducts NaN(SiMes)*.C4HsO2 ...
