Depolymerisation von Polysiloxanen und die eisenvermittelte Aktivierung kleiner Moleküle

Döhlert, Peter (2016)

Die vorliegende Arbeit umfasst im ersten Teil Studien zum Recycling von Polysiloxanen. Dazu wurde ein Protokoll zur Depolymerisation entwickelt, bei dem ein Depolymerisationsreagenz und ein Lewis S...

Synthesis and reactivity of N-heterocyclic imino-substituted group 14 compounds

Ochiai, Tatsumi (2016)

The doctoral dissertation is divided into five parts. The main goal of my dissertation is to investigate unique electron-deficient and/or low-valent Group 14 compounds by taking advantage of kineti...

Synthese und Reaktivität eines neuartigen NHC-stabilisierten Hydridosilylens

Eisenhut, Carsten (2016)

Die Arbeit ist in drei Teilabschnitte gegliedert. Im ersten Teilabschnitt dieser Arbeit wird die Synthese der neuen NHC-stabilisierten Akzeptor-freien Hydridosilylene 53 und 55 (tBu3Si(H)Si:←NHC) ...

Modulare Synthese von bioinspirierten heterobimetallischen [NiFe]-Komplexen und Untersuchung ihrer Reaktivitäten

Rudolph, Robert (2016)

Die Dissertation beschreibt den modularen Aufbau von neuen bioinspirierten heterobimetallischen NiFe-Komplexen mit den einfach herzustellenden Pinzettenliganden PNPCy- und Beta-Diketiminatoliganden...

Formation of N-heterocyclic, donor-stabilized borenium ions

Someya, Chika I.; Inoue, Shigeyoshi; Präsang, Carsten; Irran, Elisabeth; Drieß, Matthias (2011)

Cationic and zwitterionic boryl bromide species and a borenium–boryl bromide cation have been synthesised which represent new N-donor stabilised cationic boron compounds with β-diketiminate ligands...

Iron-based pre-catalyst supported on polyformamidine for C-C bond formation

Enthaler, Stephan; Krackl, Sebastian; Epping, Jan Dirk; Eckhardt, Björn; Weidner, Steffen M.; Fischer, Anna (2012)

In the present study the incorporation of iron into an organic polymer, composed of formamidine subunits [R–N[double bond, length as m-dash]C(H)–NH–R], has been examined. The catalytic ability of t...

Taming the germyliumylidene [CIGe:](+) and germathionium [CIGe=S](+) ions by donor-acceptor stabilization using 1,8-bis(tributylphosphazenyl)naphthalene

Xiong, Yun; Yao, Shenglai; Inoue, Shigeyoshi; Berkefeld, Andreas; Drieß, Matthias (2012)

The novel chlorogermyliumylidene complex L[ClGe:]+ (L = 1,8-bis(tri-n-butylphosphanzenyl)naphthalene) with a ‘naked’ Cl− as a counter anion was synthesized through reaction of L with Cl2Ge: and ful...

Dual functionality of formamidine polymers, as ligands and as bases, in ruthenium-catalysed hydrogen evolution from formic acid

Enthaler, Stephan; Junge, Henrik; Fischer, Anna; Kammer, Anja; Krackl, Sebastian; Epping, Jan Dirk (2013)

In the present study, the ruthenium-catalysed decomposition of formic acid to yield hydrogen has been examined. A ruthenium complex modified polyformamidine network was used as a solid catalyst. As...

From elusive thio- and selenosilanoic acids to copper(I) complexes with intermolecular Si=E -> Cu-O-Si coordination modes (E = S, Se)

Tan, Gengwen; Xiong, Yun; Inoue, Shigeyoshi; Enthaler, Stephan; Blom, Burgert; Epping, Jan D.; Drieß, Matthias (2013)

The facile synthesis of the first stable selenosilanoic acid–base adduct LSi([double bond, length as m-dash]Se)OH(dmap) 3 (L = CH[C(Me)NAr]2, Ar = 2,6-iPr2C6H3, dmap = 4-dimethylaminopyridine), the...

Synthesis and structure of the azidogermyliumylidene azide complex [L(N-3)Ge:]N-+(3)- with covalently and ionically bonded azide ligands at germanium(II) [L = bis(N-heterocyclic carbene)]

Xiong, Yun; Yao, Shenglai; Drieß, Matthias (2014)

Starting from the chlorogermyliumylidene chloride salt [L(Cl)Ge:]Cl (1) (L = 1,1′-methylene-3,3′-di-2,6-diisopropyl-phenylimidazole-2,2′-diylidene), the chloride ion can be easily substituted by BP...

Mechanistic studies of CO2 reduction to methanol mediated by an N-heterocyclic germylene hydride

Tan, Gengwen; Wang, Wenyuan; Blom, Burgert; Drieß, Matthias (2014)

The labile germylene hydride LCyGeH is capable of activating CO2 affording the corresponding formate LCyGeOCH([double bond, length as m-dash]O) (2) (LCy = cyclo-C6H8-1-NAr-2-C(Ph)NAr, Ar = 2,6-iPr2...
