Synthesis of Dithienylcycloalkene Molecular Switches Enabled by a Bench‐Stable Ti‐Complex

Chemistry – A European Journal, EarlyView.
Herein we report a set of cycloalkene‐bridged DTEs with ring sizes ranging from 4‐ to 7‐membered rings. The synthesis of these analogs was performed via a key McMurry coupling step, which was enabled by a practical, bench‐stable Ti(IV)‐complex. Remarkably, it is shown that the strained cyclobutene bridge outperforms other rings, even the most commonly ...

Asymmetric Hydride Shift Reactions Catalyzed by Chiral Aluminium Complexes

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
An asymmetric intramolecular hydride shift reaction has been developed that is catalyzed by Al Lewis acids in conjunction with a chiral BINOL‐derived ligand. Racemic THP substrates are transformed into cyclohexene products via an intermediate prochiral enone; which undergoes a key 1,5‐hydride shift reaction.

Reversible Nanocomposites With Carbon Nanotubes as the Diene in the Diels–Alder Reaction

Polymer Composites, EarlyView.
Scheme of the reversible nanocomposites through DA and rDA reactions with participation of carbon nanotubes. ABSTRACT Carbon nanotubes (CNTs) often require surface functionalization to facilitate uniform distribution and address issues related to aggregation. Due to the sp2 hybridized carbon atoms on their surface, CNTs readily participate in the Diels–
