Importance of Unpaired Electrons in Organic Electronics
Natalie Renuka Banerji, Mariateresa Scarongella
The first observation that PBBTPD, a low bandgap, ambipolar conjugated donor-acceptor (DA) polymer based on benzobisthiadiazole (BBT), possesses an open-shell singlet ground state as well as a thermally accessible triplet state is described. Similarly, int ...
Wiley-Blackwell2015Cyclization and annulation reactions of nitrogen-substituted cyclopropanes and cyclobutanes
Jérôme Waser, Reto Frei, Fides Benfatti, Florian Patrick Marie Daniel De la Barre De Nanteuil, Filippo De Simone, Eloísa Sofía Serrano Robledo
Cyclization and annulation reactions initiated by ring-opening of small rings, especially cyclopropanes and cyclobutanes are now well-established in synthetic chemistry. Nevertheless, the potential of aminocyclopropanes and cyclobutanes, an important subcl ...
Royal Society of Chemistry2014Ruthenium(II) and osmium(II) 1,2,3-triazolylidene organometallics: a preliminary investigation into the biological activity of 'click' carbene complexes
Paul Joseph Dyson, Tina Riedel, Kelly Joan Kilpin, Stéphanie Crot
Taking advantage of the facile and versatile synthetic properties of 'click' 1,2,3-triazolylidene N-heterocyclic carbenes (tzNHC's), a range of new organometallic Ru(II) and Os(II) arene complexes containing functionalised tzNHC ligands, [M(eta(6)-p-cymene ...
2014Diester-Substituted Aminocyclopropanes: Synthesis and Use in [3+2]-Annulation Reactions
Jérôme Waser, Florian Patrick Marie Daniel De la Barre De Nanteuil, Eloísa Sofía Serrano Robledo
In this Letter, we describe the synthesis of new donor-acceptor substituted cyclopropanes bearing various imido groups and their use in [3+2]-annulation reactions. A sequence of palladium-catalyzed vinylation and rhodium-catalyzed cyclopropanation gave acc ...
Georg Thieme Verlag2014Asymmetric Rhodium(I)-Catalyzed C-C Activations with Zwitterionic Bis-phospholane Ligands
The development of unconventional ligand scaffolds is an important aspect to alter reaction pathways of transition-metal-catalyzed reactions. The nature of the counterion of cationic metal complexes plays an important role in the catalyst reactivity. We he ...
Amer Chemical Soc2014Electrostatic and Non-covalent Interactions in Dicationic Imidazolium-Sulfonium Salts with Mixed Anions
Paul Joseph Dyson, Rosario Scopelliti, Gabor Laurenczy, Zhaofu Fei, Ning Yan
A series of thioether-functionalised imidazolium salts have been prepared and characterized. Subsequent reaction of the thioether-functionalised imidazolium salts with iodomethane affords imidazolium-sulfonium salts composed of doubly charged cations and t ...
Wiley-V C H Verlag Gmbh2014Lattice calculation of the heavy quark potential at non-zero temperature
We calculated the real and imaginary parts of the static quark-antiquark potential at T > 0 in 2 + 1 flavor QCD using correlators of Wilson lines in Coulomb gauge and lattices with temporal extent N-tau = 12. We find that the real part of the potential is ...
Elsevier Science Bv2014Insertion of Zerovalent Nickel into the N–N Bond of N-Heterocyclic-Carbene-Activated N2O
Rosario Scopelliti, Kay Severin, Euro Solari, Alexander Tskhovrebov
Metal-mediated cleavage of the N–N bond is a rarely observed phenomenon in the chemistry of nitrous oxide (N2O). We demonstrate that, upon activation of N2O with N-heterocyclic carbenes, zerovalent nickel is able to insert into the N–N bond to give nitrosy ...
