PMID: 24217215
Dalton Trans. 2014 Jan 28;43(4):1651-62. doi: 10.1039/c3dt52742e.

The sterically demanding NHCs 1,3-di-tert-butylimidazolin-2-ylidene (1a), 1,3-di-tert-butyl-4,5-dimethylimidazolin-2-yildene (1b), and also the corresponding frustrated Lewis pair combinations 1a,b/B(C6F5)3 react readily with CO2 to form the NHC·CO2 (5a,b) and the NHC·CO2·B(C6F5)3 (9a,b) adducts, respectively. However, N2O activation and isolation of the...

We describe the straightforward synthesis of a series of bis-phosphoric acids (R,R)-1 a-d, featuring two chiral 1,1'-binaphthyl-phosphoric acid units that are tethered by rigid, π-conjugated linkers. The nature of the linker has a profound influence on the properties of...

Reversible strain alignment and reshuffling of nanoplatelet stacks confined in a lamellar block copolymer matrix.

Nanoscale

Beaudoin E, Davidson P, Abecassis B, Bizien T, Constantin D.
PMID: 29095458
Nanoscale. 2017 Nov 16;9(44):17371-17377. doi: 10.1039/c7nr05723g.

We designed a nanocomposite consisting of CdSe nanoplatelets dispersed in the form of short stacks in the polybutadiene domains of a polystyrene-polybutadiene-polystyrene (SBS) thermoplastic elastomer matrix. Under strain, the material displays reversible, macroscopic anisotropic properties, e.g. the fluorescence signal....

Acute kidney injury (AKI) is a syndrome that has progressed a great deal over the last 20 years. The decrease in urine output and the increase in classical renal biomarkers, such as blood urea nitrogen and serum creatinine, have...

Stable Bromiranium Ions with Weakly-Coordinating Counterions as Efficient Electrophilic Brominating Agents.

Chemistry (Weinheim an der Bergstrasse, Germany)

Ascheberg C, Bock J, Buß F, Mück-Lichtenfeld C, Daniliuc CG, Bergander K, Dielmann F, Hennecke U.
PMID: 28636753
Chemistry. 2017 Aug 25;23(48):11578-11586. doi: 10.1002/chem.201701643. Epub 2017 Aug 09.

Electrophilic halogenating agents are an important class of reagents in chemical synthesis. Herein, we show that sterically demanding bromiranium ions with weakly coordinating counterions are highly reactive electrophilic brominating agents. Despite their high reactivity these reagents are stable, in...

Enantioselective, desymmetrizing bromolactonization of alkynes.

Journal of the American Chemical Society

J Am Chem Soc. 2013 Jun 05;135(22):8133-6. doi: 10.1021/ja402910d. Epub 2013 May 21.

Asymmetric bromolactonizations of alkynes are possible using a desymmetrization approach. The commercially available catalyst (DHQD)2PHAL promotes these cyclizations in combination with cheap NBS as a bromine source to give bromoenol lactones in high yield and with high enantioselectivity. The...

We present a new class of noninteracting kinetic energy (KE) functionals, derived from the semiclassical-atom theory. These functionals are constructed using the link between exchange and kinetic energies and employ a generalized gradient approximation (GGA) for the enhancement factor,...

Boron chemistry without the boron: In a reaction analogous to 1,1-carboboration, [Cp*2 ZrCH3 ](+) reacts with diphenylphosphino(trimethylsilyl)acetylene by 1,1-carbozirconation to give a vicinal [Zr](+) /P system. Like B/P frustrated Lewis pairs, the [Zr](+) /P system undergoes 1,2-addition to unsaturated...

Some fundamental issues in ground-state density functional theory are discussed without equations: (1) The standard Hohenberg-Kohn and Kohn-Sham theorems were proven for a Hamiltonian that is not quite exact for real atoms, molecules, and solids. (2) The density functional...
