Visualizing chemical transport from extracellular symbionts into squid host tissues using NanoSIMS

Stéphanie Kéren Cohen

Chemical communication is the basis of host-microbe interaction. Insights into this communication will provide a deeper understanding of the mechanisms that govern these complex associations, in beneficial as well as pathogenic contexts. In this dissertati ...

Gold-Catalyzed Synthesis of 1,3-Diaminopyrazoles from 1-Alkynyltriazenes and Imines

Kay Severin, Rosario Scopelliti, Loïc Nicolas Jeanbourquin, Farzaneh Fadaei Tirani

A new procedure for the synthesis of highly substituted 1,3-diaminopyrazoles is described. As substrates, we have employed 1-alkynyltriazenes and imines. The formation of pyrazoles was achieved by two-fold C–N coupling reactions in the presence of (JohnPho ...

Stereoselective synthesis of alkenes via base-metal-catalyzed addition reactions to alkynes and activation of hydrogen peroxide and carbon dioxide by iron complexes

Fedor Zhurkin

Alkene functionality can be found in the majority of natural products, drugs, catalysts and organic materials. Therefore, methods of C-C double bond formation constitute a cornerstone of organic synthesis. Selective formation of either (Z)- or (E)-isomer i ...

Delineating the Mechanism of Ionic Liquids in the Synthesis of Quinazoline-2,4(1H,3H)-dione from 2-Aminobenzonitrile and CO2

Gabor Laurenczy, Paul Joseph Dyson, Shoubhik Das, Sami Manoubi Armand Chamam, Martin Hulla

Ionic liquids (ILs) are versatile solvents and catalysts for the synthesis of quinazoline-2,4-dione from 2-aminobenzonitrile and CO2. However, the role of the IL in this reaction is poorly understood. Consequently, we investigated this reaction and showed ...

Solvent effects in catalysis: rational improvements of catalysts via manipulation of solvent interactions

Paul Joseph Dyson, Philip Gregory Jessop

In homogeneous catalysis, the main emphasis on improving catalyst performance (rate, yield and selectivity) is directed towards manipulation of the ligands. The steric and electronic effects of ligands are extremely well understood and the rational design ...

Synthesis, structure, and catalytic properties of palladium complexes containing bis(phosphino)-amine ligands

Kurt Schenk, Farzaneh Fadaei Tirani

Two N,N-bis(diphenylphosphino)-amine ligands [amine = 4-aminomorpholine (L-1) or 1-amino-4-methylpiperazine (L-2)] and their Pd(II) complexes were synthesised and characterised by IR and NMR spectroscopies. The structures of ligand L-1 and both complexes C ...
