Transition Metal Catalysis on Olefins: Some Considerations Relative to Migratory Insertion
CHIMIA, 2001 Olefin migratory insertion into a metal–hydrogen or a metal–carbon bond is an ubiquitous step in olefin coordination catalysis by transition metal complexes. When the catalytic system has element(s) of chirality, and when the two carbon atoms of

Radical Cascade Combining Cross‐Olefin Coupling with the Smiles‐Truce Rearrangement
Angewandte Chemie International Edition, EarlyView.We present a cobalt‐catalysed radical cascade that efficiently merges two alkene starting materials to form multiple bonds in a single step. The process begins with a cobalt‐catalysed hydrogen‐atom transfer‐to a styrene double bond, followed by a Giese addition.

A Dithio Vinylthio C2 Synthon Enabling Crystalline and Luminescent Sulfur‐Decorated Polymers
Angewandte Chemie International Edition, EarlyView.Transforming CaC2 into a modular C2 building block enables the synthesis of α,ω‐bis(vinylthio) monomer and its conversion into crystalline, sequence‐defined sulfur‐decorated polymers. Their dense thioether clustering induces nonconventional luminescence and provides structure–function control in a more‐sustainable polymer platform.
