Chemistry – A European Journal, EarlyView.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.

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.A less hindered and highly nucleophilic N‐heterocyclic carbene (NHC) boryl anion is generated at room temperature by reacting sp2–sp3 diboron reagent (NHC)BH2Bpin with KOtBu. This highly reactive anion demonstrates broad reactivity with various electrophiles, including those traditionally considered inert, enabling their efficient borylation.

Journal of Lipid Research, 1974 Many anaerobic bacteria have a high proportion of 1-alk-1′-enyl ethers (plasmalogens) among their phospholipids. We have examined the effects of growth temperature on the phospholipid, fatty acid, and alk-1-enyl group compositions of Clostridium ...

Pd‐Catalyzed C─C Bond Borylation of Biphenylenes Leading to Tri‐Ortho‐Substituted Biaryls
Chemistry – A European Journal, EarlyView.Palladium‐catalyzed ring‐opening C─C borylation of 1‐substituted biphenylenes yields a range of o,o,o′‐trisubstituted biaryls with two ortho‐boryl groups via selective cleavage of the least hindered C─C bond. The resulting diborylated products are readily amenable to sequential, site‐selective postfunctionalization.

Chemistry – A European Journal, EarlyView.We report an efficient method for late‐stage installation of “clickable” alkyne groups into diverse (hetero)arenes. Using a dual‐ligand palladium catalyst that combines an NASA ligand with an N‐heterocycle, an acrylate unit bearing a terminal alkyne can be introduced via nondirected C─H activation.

Organophotocatalyst Enabled Deoxycyclopropanation of Alcohols
Advanced ScienceCyclopropane fragments, which widely exist in marketed drugs and natural products, can confer special pharmacological properties to small‐molecule drugs. Therefore, developing methods to construct cyclopropanes is of great significance. Nevertheless, the

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance
Chemistry – A European Journal, EarlyView.This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

Iron‐Mediated Electrochemical Cyclopropanation of Borodiiodomethane with Alkenes†
Chinese Journal of Chemistry, EarlyView.This work describes an electrochemical iron‐mediated cyclopropanation of borodiiodomethane with alkenes, resulting in the formation of boro‐substituted cyclopropanes. A key feature of this study is the unexpected discovery that the cathodically generated iron ion coordinates with a biquinoline ligand in situ, facilitating the electrochemical ...
