Aromatic Homologation by Non- Chelate- Assisted RhIII- Catalyzed C -H Functionalization of Arenes with Alkynes

Larger condensed arenes are of interest owing to their electro- and photochemical properties. An efficient synthesis is the catalyzed aromatic annulation of a smaller arene with two alkyne molecules. Besides difunctionalized starting materials, directed CH ...

Mechanistic Insights into Nickamine-catalyzed Alkyl-Alkyl Cross-coupling Reactions

Xile Hu, Jan Breitenfeld

Within the last decades the transition metal-catalyzed cross-coupling of non-activated alkyl halides has significantly progressed. Within the context of alkyl-alkyl cross-coupling, first row transition metals spanning from iron, over cobalt, nickel, to cop ...

Reaction Mechanism and Catalytic Fingerprint of Allantoin Racemase

Matteo Dal Peraro, Marco Stenta, Thomas Lemmin, Matteo Thomas Degiacomi, Christophe Bovigny

The stereospecific oxidative decomposition of urate into allantoin is the core of purine catabolism in many organisms. The spontaneous decomposition of upstream intermediates and the nonenzymatic racemization of allantoin lead to an accumulation of (R)-all ...

Access to beta-Lactams by Enantioselective Palladium(0)-Catalyzed C(sp(3))-H Alkylation

Nicolai Cramer, Tanguy Jean Daniel Saget, Julia Pedroni, Michele Boghi

beta-Lactams are very important structural motifs because of their broad biological activities as well as their propensity to engage in ring-opening reactions. Transitionmetal- catalyzed C-H functionalizations have emerged as strategy enabling yet uncommon ...

Highly Enantioselective Rhodium(I)-Catalyzed Carbonyl Carboacylations Initiated by C-C Bond Activation

Nicolai Cramer, Laetitia Marie Mélanie Souillart

The lactone motif is ubiquitous in natural products and pharmaceuticals. The Tishchenko disproportionation of two aldehydes, a carbonyl hydroacylation, is an efficient and atom-economic access to lactones. However, these reaction types are limited to the t ...

Redox chemistry and metal–insulator transitions intertwined in a nano-porous material

Berend Smit

Metal-organic frameworks are nano-porous adsorbents of relevance to gas separation and catalysis, and separation of oxygen from air is essential to diverse industrial applications. The ferrous salt of 2,5-dihydroxy-terephthalic acid, a metal-organic framew ...

Dynamics of gas phase Ne* + NH3 and Ne* + ND3 Penning ionisation at low temperatures

Andreas Osterwalder, Justinas Jankunas, Benjamin Bertsche

Two isotopic chemical reactions, Ne* + NH_3, and Ne* + ND_3, have been studied at low collision energies by means of a merged beams technique. Partial cross sections have been recorded for the two reactive channels, namely, Ne* + NH_3 → Ne + NH^+_3 + e −, ...

Rhodium(III)/Copper(II)-Promoted trans-Selective Heteroaryl Acyloxylation of Alkynes: Stereodefined Access to trans-Enol Esters

Nicolai Cramer, Van Manh Pham

Enol esters are versatile synthetic building blocks which can be elaborated by a wide variety of transformations. The classical synthesis by O-selective enolate acylation often hampers control of the E/Z selectivity with highly substituted substrates. A rh ...
