Synthesis of Unusual Oxime Ethers by Reaction of Tetranitromethane with B-Alkylcatecholboranes

Philippe Renaud, Kurt Schenk

The reaction of tetranitromethane with B-alkylcatecholboranes leads to the formation of unusual dinitrooxime ethers. A tentative mechanism is provided, which suggests the involvement of extremely fast addition of alkyl radicals to tetranitromethane. The su ...

Low-cost industrially available molybdenum boride and carbide as “platinum-like” catalysts for the hydrogen evolution reaction in biphasic liquid systems

Hubert Girault, Xile Hu, Kurt Schenk, Heron Vrubel, Véronique Amstutz, Micheal Diarmaid Scanlon

Rarely reported low-cost molybdenum boride and carbide microparticles, both of which are available in abundant quantities due to their widespread use in industry, adsorb at aqueous acid–1,2-dichloroethane interfaces and efficiently catalyse the hydrogen ev ...

A four-component organogel based on orthogonal chemical interactions

Kay Severin, Kurt Schenk, Nicolas Luisier

A thermoresponsive organogel was obtained by orthogonal assembly of four compounds using dynamic covalent boronate ester and imine bonds, as well as dative boron-nitrogen bonds. It is shown that the gel state can be disrupted or reinforced by chemicals whi ...

The 2SO Skew-Boat Conformation in L-Iduronic Acid

Kurt Schenk

Crystal clear: After two decades of controversy the elusive skew-boat conformation of L-iduronic acid (see picture) was finally ascertained at atomic resolution in a synthetic, substituted disaccharide. This highly flexible compound crystallizes in two dim ...

Dative boron–nitrogen bonds in structural supramolecular chemistry: multicomponent assembly of prismatic organic cages

Rosario Scopelliti, Kay Severin, Kurt Schenk, Erin Sheepwash, Burçak Içli

The multicomponent reaction of diboronic acids with a catechol and a tripyridyl linker results in the formation trigonal prismatic cages. The cages feature six dative boron–nitrogen bonds as structure-directing elements. The size of the cages can be varied ...

Total Synthesis of (+/-)-Cylindricine C

Philippe Renaud, Kurt Schenk

A concise synthesis of (+/-)-cylindricine C and its C(13)-epimer is described. Starting from 1-octyne, cylindricine C and 13-epi-cylindricine C were prepared in 11% and 15% yields, respectively. The synthesis involves the preparation of the central tricycl ...
