Divergent Synthesis of Densely Substituted Arenes and Pyridines via Cyclotrimerization Reactions of Alkynyl Triazenes
Kay Severin, Nicolai Cramer, Carl Thomas Bormann, Florian Gérald Abela, Jin Fay Tan, Frederick Mark Chadwick
Densely substituted fused aromatic triazenes can be prepared by [2 + 2 + 2] cyclotrimerization reactions of 1-alkynyl triazenes. The Cp*Ru-catalyzed cyclization proceeds well with both simple alkynyl triazenes and tethered 1-diynyl triazenes. Attractively, ...
2019Electronic Structures and Catalytic Activities of Niobium Oxides as Electrocatalysts in Liquid-Junction Photovoltaic Devices
Ulf Anders Hagfeldt, Sheng Meng, Sining Yun, Hang Liu
Two types of nanosized niobium oxides and their composites, pseudohexagonal Nb2O5 (TT-Nb2O5), monoclinic NbO2 (M-NbO2), and the coexistence of TT-Nb2O5 and M-NbO2 (TT-Nb2O5/M-NbO2), are successfully synthesized through the urea-metal chloride route, and th ...
WILEY-V C H VERLAG GMBH2019Synthesis of Diversely Functionalized Oxindoles Enabled by Migratory Insertion of Isocyanide to a Transient σ-Alkylpalladium(II) Complex
Qian Wang, Jieping Zhu, Wangqing Kong
Palladium-catalyzed intramolecular carbopalladation of N-aryl acrylamides followed by migratory insertion of an isocyanide-coordinated C(sp3)-Pd intermediate afforded an alkylimidoyl-Pd(II) complex, which can be intercepted by a nucleophile, including hete ...
Wiley-Blackwell2016Structurally Diverse Cyclisation Linkers Impose Different Backbone Conformations in Bicyclic Peptides
Christian Heinis, Alessandro Angelini, Shiyu Chen, Julia Morales Sanfrutos
Combinatorial libraries of structurally diverse peptide macrocycles offer a rich source for the development of high-affinity ligands to targets of interest. In this work we have developed linkers for the generation of genetically encoded bicyclic peptides ...
2012Electrophilic alkynylation: the dark side of acetylene chemistry
In addition to the well-established nucleophilic alkynylation, the use of electrophilic alkynes can expand tremendously the scope of acetylene transfer reactions. The use of metal catalysis has recently led to a rebirth of this research area. Halogenoalkyn ...
Royal Society of Chemistry2012New Acetylene Chemistry
This thesis is divided in seven main chapters including an introduction about the state of the art in the field, four main chapters describing the main part of the work, a short insight on the implications of the presented results for other research projec ...
EPFL2011Formation of aminosilane-oxide interphases
Véronique Michaud, Yves Leterrier, Gabrielle Pax
The aim of this work is to understand the interactions and interphase formation mechanisms between a liquid aminosilane oligomer (γ -APS) and glass, steel or gold surfaces as a function of the pH of the liquid aminosilane. When basic liquid γ -APS (pH 11.4 ...
