2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

ChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...

Functional polymer materials containing heavy group‐14 elements focusing on germanium and tin

Smart Molecules, EarlyView.
The synthesis, functions, and applications of the polymers containing heavy group 14 elements focusing on germanium and tin are outlined. Owing to their large atomic radii and weak binding energies, the polymers show unique properties: chromism, luminescence, carrier mobility, and reactivity to produce radials and higher coordinated states.
