Ultrahigh bandwidth spin noise spectroscopy: detection of large g-factor fluctuations in highly-n-doped GaAs.

Physical review letters

Berski F, Kuhn H, Lonnemann JG, Hübner J, Oestreich M.
PMID: 24237545
Phys Rev Lett. 2013 Nov 01;111(18):186602. doi: 10.1103/PhysRevLett.111.186602. Epub 2013 Oct 29.

We advance all optical spin noise spectroscopy (SNS) in semiconductors to detection bandwidths of several hundred gigahertz by employing a sophisticated scheme of pulse trains from ultrafast laser oscillators as an optical probe. The ultrafast SNS technique avoids the...

Phosphinic Amide as Directing Group Enabling Palladium(II)-Catalyzed ortho C-H Alkenylation of Anilines without and with Alkylation at the Nitrogen Atom.

Chemistry, an Asian journal

Jiao LY, Ferreira AV, Oestreich M.
PMID: 26370493
Chem Asian J. 2016 Feb 04;11(3):367-70. doi: 10.1002/asia.201500829. Epub 2015 Sep 24.

A phosphinic amide is introduced as a directing group for the ortho C-H alkenylation of anilines. The new donor group distinguishes itself from existing ones by assisting the C-H bond activation of anilides without (NH group) and with alkylation...

Asymmetric catalysis with silicon-based cuprates: enantio- and regioselective allylic substitution of linear precursors.

Chemistry (Weinheim an der Bergstrasse, Germany)

Hensel A, Oestreich M.
PMID: 25965581
Chemistry. 2015 Jun 15;21(25):9062-5. doi: 10.1002/chem.201501371. Epub 2015 May 12.

An enantio- and regioselective allylic silylation of linear allylic phosphates that makes use of catalytically generated cuprate-type silicon nucleophiles is reported. The method relies on soft bis(triorganosilyl) zincs as silicon pronucleophiles that are prepared in situ from the corresponding...

Friedel-Crafts-Type Intermolecular C-H Silylation of Electron-Rich Arenes Initiated by Base-Metal Salts.

Angewandte Chemie (International ed. in English)

PMID: 26821860
Angew Chem Int Ed Engl. 2016 Feb 24;55(9):3204-7. doi: 10.1002/anie.201510469. Epub 2016 Jan 28.

An electrophilic aromatic substitution (SE Ar) with a catalytically generated silicon electrophile is reported. Essentially any commercially available base-metal salt acts as an initiator/catalyst when activated with NaBAr(F)4. The thus-generated Lewis acid then promotes the SE Ar of electron-rich...

Catalytic Friedel-Crafts C-H Borylation of Electron-Rich Arenes: Dramatic Rate Acceleration by Added Alkenes.

Angewandte Chemie (International ed. in English)

Yin Q, Klare HF, Oestreich M.
PMID: 28244623
Angew Chem Int Ed Engl. 2017 Mar 20;56(13):3712-3717. doi: 10.1002/anie.201611536. Epub 2017 Feb 28.

In the electrophilic C-H borylation of electron-rich aromatic compounds with catecholborane, the catalytic generation of the boron electrophile is initiated by heterolysis of the B-H bond by various Lewis and Brønsted acids, with a boronium ion formed exclusively. After...

Cooperative Catalysis at Metal-Sulfur Bonds.

Cooperative catalysis has attracted tremendous attention in recent years, emerging as a key strategy for the development of novel atom-economic and environmentally more benign catalytic processes. In particular, Noyori-type complexes with metal-nitrogen bonds have been extensively studied and evolved...

Hydrogenation and Transfer Hydrogenation Promoted by Tethered Ru-S Complexes: From Cooperative Dihydrogen Activation to Hydride Abstraction/Proton Release from Dihydrogen Surrogates.

Hydrogenation and transfer hydrogenation of imines with cyclohexa-1,4-dienes, as well as with a representative Hantzsch ester dihydrogen surrogate, are reported. Both processes are catalyzed by tethered Ru-S complexes but differ in the activation mode of the dihydrogen source: cooperative...
