SmI₂/Sm-Induced Reductive Silacyclization of Alkene/Diene Derivatives Using Dichlorosilanes or 1,2-Dichlorodisilanes via Reductive Radical-Polar Crossover. [PDF]

Chemistry
A SmI2/Sm‐mediated silacyclization unlocks a concise route to 4–7‐membered silacycles from simple unsaturated substrates and dichlorosilanes/disilanes. The complementary functions of samarium reductants trigger a reductive radical–polar crossover, offering a versatile strategy for constructing multiple Si─C bonds efficiently.

Vacuum-Nitrogen Assisted (VANS) Topotactical Deintercalation for Extremely Fast Production of Functionalized Silicene Nanosheets. [PDF]

Small
Silicene, an analog of graphene with silicon atoms arranged in a honeycomb lattice, shows promise for electronic devices and photocatalysis. A new rapid VANS (vacuum‐nitrogen assisted) protocol accelerates its production by efficiently removing hydrogen and maintaining inert conditions.

Perfluorinated Organosilicons Enabling Low-Loss Ferroelectric Polymer Composites for Efficient Energy Storage and Electroluminescence. [PDF]

Adv Sci (Weinh)
Ferroelectric polymers for energy storage and conversion are suffering from severe energy losses despite their highly electroactive functions. Here an organic–inorganic hybrid—perfluorinated polyhedral oligomeric silsesquioxane (F‐POSS) is synthesized to markedly suppress losses in ferroelectric polymers for achieving efficient energy storage and ...
