Biological membranes play a key role for the function of living organisms. Thus, many artificial systems have been designed to mimic natural cell membranes and their functions. A useful concept for the preparation of fun...
Versatile precursor to metal complexes: The lithiated N-heterocyclic carbene derivative [Li(imino-imidide)(tmeda)] (imino-imidide=4-(2,6-diisopropylphenylimino)imidazol-2-ylidenide), obtained by deprotonation and lithiat...
Smooth as isatin! A straightforward synthesis of spirocyclic oxindole-dihydropyranones through an N-heterocyclic-carbene-catalyzed [4+2] annulation of alpha-bromo-alpha,beta-unsaturated aldehydes or alpha,beta-dibromoald...
A good move: A copper-catalyzed intramolecular oxidative C H functionalization of 2-aminobenzophenone affords two regioisomeric acridones (see scheme). The reaction involves an unusual pseudo-1,2-migration of R-2 group(s...
Anyone for a pi-type sandwich? A luminescent indicator was developed based on the potassium-binding-induced conformational change of a macrocyclic terbium complex. The indicator adopts a random coil conformation in the a...
Control by encapsulation: A dimeric capsule assembled from a tripodal host by van der Waals forces can stabilize a series of reactive molecules, such as cyclopentadiene and trichlorosilane, in the crystalline state even ...
Cool cats: 1,1'-Bi-2-naphthol and vaulted 3,3'-biphenanthrol-type bisphosphorylimides enabled the atom-economical and highly enantioselective Friedel-Crafts reaction between indoles and N-tosylimines with a low catalyst ...
At the gate: Colorimetric enantiorecognition of one oligopeptide was realized by virtue of a D-enantiomer specific DNA aptamer as chiral selector and unmodified gold nanoparticles as indicator. Oligopeptide enantiomers a...
Heavy stuff: A triethylamine-mediated H-D exchange reaction for the conversion of unlabeled alkynes (1) into [D-1]alkynes ([D-1]-1) in a mixture of D2O/THF has been developed. Furthermore, the efficient preparation of si...
Getting selectively organized: Molecules of bis-pyridyl dienes have been stereoselectively photodimerized to form their strained double [2+2] reaction products by using argentophilic forces (see scheme). A pronounced inf...
Nanosheet-assembled hierarchical V2O5 hollow microspheres are successfully obtained from V-glycolate precursor hollow microspheres, which in turn are synthesized by a simple template-free solvothermal method. The structu...
As the properties of nanomaterials are strongly dependent on their size, shape and nanostructures, probing the relations between macro-properties and nanostructures is challenging for nanoscientists. Herein, we deliberat...
Various thermally stable energetic polynitro-aryl-1,2,3-triazoles have been synthesized through Cu-catalyzed [3+2] cycloaddition reactions between their corresponding azides and alkynes, followed by nitration. These comp...
Halogen bonds between the trifluoromethyl halides CF3Cl, CF3Br and CF3I, and dimethyl ether, dimethyl sulfide, trimethylamine and trimethyl phosphine were investigated using Pearson's hard and soft acids and bases (HSAB)...
Chondroitin sulfate-E (CS-E) oligosaccharidic analogues (di to hexa) were prepared from lactose. In these compounds, the 2-acetamido group was replaced by a hydroxyl group. This modification speeded up the synthesis, and...
Controlled chain-scission of polybutadiene (PB), polyisoprene, and poly(styrene-co-butadiene), induced by bis(cyclopentadienyl) zirconium hydrochloride (Cp2ZrHCl), was revealed at room temperature. The chain-scission rea...
