Azetidinylideneketenimines as a Multimodal Synthetic Platform: Coordination Chemistry and Cycloaddition‐Triggered Transformations

Angewandte Chemie, EarlyView.
Cross‐coupling/homologation sequence between a stable three‐membered‐ring carbene and isocyanides enables facile and rapid access to novel methyleneketenimines and the first bis(methyleneketenimine). Reactivity studies gave rise to the first methyleneketenimine‐transition metal complexes, unique multimodal reactivity ranging from CO2, isocyanate ...

Deprotonative C(sp3)/C(sp2)–H (Multi)Silylation of (Hetero)Arenes Mediated by NaTMP

Angewandte Chemie, EarlyView.
An operationally simple protocol using a strongly basic sodium amide in combination with sterically emcumbered silicon electrophiles enables the deprotonative C–H (multi)silylation of a myriad of (hetero)arenes. Mechanistic investigations highlight the pivotal role of steric and coordination effects in controlling the regioselectivity and efficiency of

Probing Steady‐State Carrier Properties and Charge Transport in Covalent Organic Framework by Frequency‐Domain Terahertz Spectroscopy

Angewandte Chemie, EarlyView.
This work reports a combined frequency‐domain and time‐domain terahertz (THz) spectroscopic approach to elucidate intrinsic carrier properties and transport mechanisms in framework materials over the extended 0.5–20 THz region. Subtle structural and chemical variations are shown to strongly influence THz charge‐transport behavior across the far ...

Mixed‐Functionalized Acylgermanes Result in Wavelength‐Controlled Fragmentation

Angewandte Chemie, EarlyView.
Selective radical generation from PEG‐acylgermanes is achieved by controlling the used wavelength. Distinct aryl‐carbonyl units undergo wavelength‐dependent α‐cleavage, producing radicals with different reactivities. UV/Vis, TD‐DFT, and photo‐CIDNP spectroscopy confirm that small adjustments in light input directly dictate radical identity and ...
