Assessing Benzene Dimer Interactions in Solution With a Molecular Balance

Chemistry – A European Journal, EarlyView.
The Gecko in the ToC was generated with Canva (31.03.2025 11:00 pm), the remaining graphics by the authors. ABSTRACT We present a combined experimental and computational study of a 1,4/1,6‐dibenzyl substituted cyclooctatetraene (COT)‐based molecular balance as a model to assess the benzene dimer interactions in solution.

Catalytic Generation of Cationic Gold Carbene Complexes From 7‐Alkynylnorbornadienes and Their Intermolecular Cyclopropanation With Alkenes

Chemistry – A European Journal, EarlyView.
Efficient cationic gold(I)‐catalyzed intermolecular cyclopropanation of 7‐alkynylnorbornadiene derivatives has been developed. This methodology offers the synthesis of a new class of norbornene derivatives in high yield with excellent diastereoselectivity.

Organocatalytic Formal (3+2+1)‐Cycloaddition of Allenoates, Michael Acceptors, and Carbaldehydes

Chemistry – A European Journal, EarlyView.
The use of secondary amine Lewis base organocatalysts allows for the unprecedented activation of allenoates for formal (3+2+1)‐cycloadditions with Michael acceptors and aromatic carbaldehydes. ABSTRACT Employing secondary amines as covalently interacting Lewis basic organocatalysts allows for the activation of electron‐deficient allenes (allenoates ...

Germylium Catalyzed Dehydrofluorination Reactions of Fluorinated Alkanes

Chemistry – A European Journal, EarlyView.
Dehydrofluorination reactions of fluorinated alkanes catalyzed by germylium ions are reported. Computational studies of the mechanism revealed an E2 type mechanism involving a germane as a base to facilitate olefin formation in competition with an SN2 mechanism for hydrodefluorination.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.
