Synthesis and Characterization of Iron-Nitrogen-Doped Graphene/Core-Shell Catalysts: Efficient Oxidative Dehydrogenation of N-Heterocycles.

Journal of the American Chemical Society

Cui X, Li Y, Bachmann S, Scalone M, Surkus AE, Junge K, Topf C, Beller M.
PMID: 26230874
J Am Chem Soc. 2015 Aug 26;137(33):10652-8. doi: 10.1021/jacs.5b05674. Epub 2015 Aug 11.

An important goal for nanocatalysis is the development of flexible and efficient methods for preparing active and stable core-shell catalysts. In this respect, we present the synthesis and characterization of iron oxides surrounded by nitrogen-doped-graphene shells immobilized on carbon...

Electric-field-induced lamellar to hexagonally perforated lamellar transition in diblock copolymer thin films: kinetic pathways.

Physical chemistry chemical physics : PCCP

Mukherjee A, Ankit K, Reiter A, Selzer M, Nestler B.
PMID: 27722519
Phys Chem Chem Phys. 2016 Sep 14;18(36):25609-25620. doi: 10.1039/c6cp04903f.

Symmetric block-copolymers, hitherto, are well known to evolve into parallel, perpendicular and mixed lamellar morphologies under the concomitant influence of an electric field and substrate affinity. In the present work, we show that an additional imposed confinement can effectuate...

Highly efficient four-component synthesis of 4(3H)-quinazolinones: palladium-catalyzed carbonylative coupling reactions.

Angewandte Chemie (International ed. in English)

He L, Li H, Neumann H, Beller M, Wu XF.
PMID: 24338922
Angew Chem Int Ed Engl. 2014 Jan 27;53(5):1420-4. doi: 10.1002/anie.201308756. Epub 2013 Dec 13.

Given the importance of quinazolinones and carbonylative transformations, a palladium-catalyzed four-component carbonylative coupling system for the synthesis of diverse 4(3H)-quinazolinone in a concise and convergent fashion has been developed. Starting from 2-bromoanilines (1 mmol), trimethyl orthoformate (2 mmol), and...

A convenient and selective palladium-catalyzed aerobic oxidation of alcohols.

Chemistry (Weinheim an der Bergstrasse, Germany)

Gowrisankar S, Neumann H, Gördes D, Thurow K, Jiao H, Beller M.
PMID: 24127139
Chemistry. 2013 Nov 18;19(47):15979-84. doi: 10.1002/chem.201302526. Epub 2013 Oct 14.

An efficient procedure for the oxidation of primary and secondary alcohols to aldehydes and ketones, respectively, with molecular oxygen under ambient conditions has been achieved. By applying catalytic amounts of Pd(OAc)2 in the presence of tertiary phosphine oxides (O=PR3)...

Connecting the wakefield instabilities in dusty plasmas.

Physical review. E, Statistical, nonlinear, and soft matter physics

Melzer A.
PMID: 25493893
Phys Rev E Stat Nonlin Soft Matter Phys. 2014 Nov;90(5):053103. doi: 10.1103/PhysRevE.90.053103. Epub 2014 Nov 17.

The wakefield, or ion focus, formed by ions streaming past dust particles trapped in the plasma sheath leads to two types of instabilities: the Schweigert instability in multilayer systems and the mode-coupling instability that already appears in single-layer dust...

Current developments in pediatric liver transplantation.

World journal of hepatology

Hackl C, Schlitt HJ, Melter M, Knoppke B, Loss M.
PMID: 26085910
World J Hepatol. 2015 Jun 18;7(11):1509-20. doi: 10.4254/wjh.v7.i11.1509.

In 1953, the pioneer of human orthotopic liver transplantation (LT), Thomas E Starzl, was the first to attempt an orthotopic liver transplant into a 3 years old patient suffering from biliary atresia. Thus, the first LT in humans was...

Non-Pincer-Type Manganese Complexes as Efficient Catalysts for the Hydrogenation of Esters.

Angewandte Chemie (International ed. in English)

van Putten R, Uslamin EA, Garbe M, Liu C, Gonzalez-de-Castro A, Lutz M, Junge K, Hensen EJM, Beller M, Lefort L, Pidko EA.
PMID: 28429449

Catalytic hydrogenation of carboxylic acid esters is essential for the green production of pharmaceuticals, fragrances, and fine chemicals. Herein, we report the efficient hydrogenation of esters with manganese catalysts based on simple bidentate aminophosphine ligands. Monoligated Mn PN complexes...
