Fluorogenic Sydnones for Bioorthogonal Labeling of DNA
Chemistry – A European Journal, EarlyView.Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

Stereochemical Control in the Matteson Reaction
Chemistry – A European Journal, EarlyView.The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Interplay of Bridge Topology and Conformation in Phenylene‐Bridged Trityl Diradicals
Chemistry – A European Journal, EarlyView.We present a meta‐phenylene‐bridged trityl diradical that exhibits an unexpectedly weak antiferromagnetic exchange coupling J with a strong environment‐dependent magnitude. Combined VSM, EPR, DFT, and MD studies reveal that structural flexibility modulates σ‐, π‐, and through‐space exchange contributions, highlighting the crucial role of geometry in ...

Deriving General Energy Predictors for Pnictogen Bonding
Chemistry – A European Journal, EarlyView.This study derives general energetic predictors for pure pnictogen bonds from nitrogen to bismuth based on the potential energy density at the bond critical point. The research highlights the increasing occurrence of secondary interactions for heavier elements.

Chemistry – A European Journal, EarlyView.Several new chiral cyclic hypervalent iodine(III) reagents have been synthesized and characterized. Carbon‐based ligands were successfully installed onto the hypervalent iodine centers, giving thus access to novel chiral cyano‐, trifluoromethyl‐ or alkynyl‐bearing λ3‐iodanes.
