Angewandte Chemie, EarlyView.Single‐electron transfer‐mediated reductive carbonyl–olefin couplings are valuable carbon–carbon bond forming reactions. However, limitations persist for couplings of aliphatic aldehydes with electron‐deficient olefins. Here, we report a simple, photocatalyst‐free protocol that overcomes these limitations by using a Hantzsch ester anion as a ...

Mechanically Activated Luminescence in Polyurethanes Incorporating Calixarene Mechanophores
Angewandte Chemie, EarlyView.The conformational flexibility of a calix[4]arene is exploited to obtain a reversible mechanoluminophore featuring a pyrene excimer couple at the upper rim. Stretching a linear polyurethane incorporating such mechanophore results in luminescence color change from yellow–green to blue, consistent with a force‐induced conformational motion of the ...

Isolation and Reactivity of a Square‐Planar Trisamido Silane
Angewandte Chemie International Edition, EarlyView.We report the synthesis and comprehensive characterisation of a square‐planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N‐pincer ligand. This system enables element–ligand cooperative reactivity as an alternative to silicon‐centred redox chemistry, illuminating a largely unexplored regime in high‐valent silicon ...
