Angewandte Chemie, EarlyView.An iron‐photocatalyzed unsymmetrical 1,2‐hetero(atom)difunctionalization of alkenes enables to install orthogonal C–Cl and C–O (alkoxyamine) handles which provides access to diverse nucleophiles via complementary reactivity (SN and photoredox) at two distinct sites. Detailed mechanistic studies elucidate interesting features of the iron catalytic cycle.

Angewandte Chemie, EarlyView.A regioselective ruthenium catalyzed trans‐hydrosilylation of propargyl alcohols followed by a 1,3‐Brook rearrangement opens access to reactive organocopper intermediates, which evolve upon warming into allenes with strict chirality transfer to the emerging axis; alternatively, these reactive species can be trapped with a large variety of electrophiles

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).

Beyond the Oxo‐Wall: Synthesis and Reactivity of a Six‐Coordinate Formally CoIV‐Oxo Complex
Angewandte Chemie, EarlyView.We present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)]+ (1), which exists as an admixture of CoIV‐oxo and CoIII‐oxyl resonance structures. Complex 1 is capable of performing oxygen atom transfer reactions and abstracting moderately strong hydrogen atoms at rates faster than other characterized CoIV‐oxo compounds.
