A novel Fe-NHC catalytic system allows the alkyl-alkyl cross-coupling reaction of alkyl halides and alkylmagnesium reagents has been developed. To our knowledge, this is the first Fe-catalysed Kumadatype coupling for the formation of C(sp 3 )-C(sp 3 ) bonds in the presence of functional groups. The process takes place under mild conditions, avoiding the formation of b-elimination products.Mechanistic studies suggest the intermediacy of Fe(I) complexes, formed by reduction with the Grignard reagent, as the active species.

A new catalytic system for the photooxidation of sulfides based on Pt(ii) complexes is presented. The catalyst is capable of oxidizing a large number of sulfides containing aryl, alkyl, allyl, benzyl, as well as more complex structures such as heterocycles and methionine amino acid, with complete chemoselectivity. In addition, the first sulfur oxidation in a continuous flow process has been developed.

Mit Erythrozyten als Templat lassen sich Polymeroberflächen prägen (siehe Rasterkraftmikroskopie‐Aufnahme). Trotz der hohen Flexibilität dieser Zellen zeigen die Abdrücke eine beträchtliche Selektivität für die verschiedenen Blutgruppen, wie aus den Sensorantworten mit der Quarzmikrowaage (Einschub) hervorgeht. So werden durch den Prägeprozess selektive synthetische Antikörper für die Erythrozytenantigene erzeugt.

A series of novel ligands based on N-heterocyclic carbene and sulfoxide functionalities have been prepared and characterized. Pd(II) complexes have been synthesized by transmetalation from the corresponding NHC−Ag derivatives, and their behavior as catalysts has been studied in arene C−H bond oxidative activation. Studies conducted toward the elucidation of the reaction mechanism of the acetoxylation suggest a C−H activation step at Pd(IV) rather than Pd(II) intermediates.
