Photochemical Reaction Discovery Enabled by the Dynamic Speciation of Copper Complexes

Angewandte Chemie, EarlyView.
A strategy for accelerated photochemical reaction discovery is reported that harnesses the dynamic speciation of copper complexes, driven by their labile metal–ligand bonds. This platform simplifies reaction screening by combining an earth‐abundant copper(II) salt with commercially available ligands, which reversibly generate multiple catalytic species

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

Angewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Scalable ω‐Substituted α‐Olefins via Living Chain Transfer Telomerization: A Platform for Next Generation Polyolefins

Angewandte Chemie, EarlyView.
A highly versatile and general strategy is presented for the scalable production of practical quantities of ω‐substituted α‐olefins using tris(ω‐substituted alkyl)aluminum telogens that are readily available through a “green” synthesis from commodity triisobutylaluminum and ethene as the taxogen. These new α‐olefins can be designed and used as monomers

Light‐Gated Control of Brownian Rotation by a Molecular Motor

Angewandte Chemie, EarlyView.
A light‐driven molecular motor acts as a reversible steric gate for a nearby Brownian rotor. Photoisomerization switches the rotor between fast and hindered rotational regimes by modulating steric congestion around the rotational axis. The motor–rotor architecture enables a five‐order‐of‐magnitude difference in the rotational barrier, demonstrating ...

Reactions of Terminal Olefins With Iron Carbenes

Angewandte Chemie, EarlyView.
Iron carbenes react with terminal olefins and show productive metathesis or metathesis‐divergent pathways depending on the nature of the olefin. Reactions proceed through 2π + 2π cycloadditions to generate transient metallacyclobutane intermediates that undergo cycloreversion to generate the metathesis product or the metathesis‐divergent β‐hydride ...
