Iron‐Photocatalyzed Alkene Chloroaminoxylation: A Platform for Orthogonally Activatable Building Blocks

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
An iron‐photocatalyzed unsymmetrical 1,2‐hetero(atom)difunctionalization of alkenes enables to install orthogonal C–Cl and C–O (alkoxyamine) handles which provides access to diverse nucleophiles via complementary reactivity (SN and photoredox) at two distinct sites. Detailed mechanistic studies elucidate interesting features of the iron catalytic cycle.

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Created Ex Nihilo: A Near‐Infrared Afterglow Luminescent Framework of Imidazole Derivatives for Bioimaging

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
A series of Ir(III) complexes (Ir‐1‐Ir‐4) based on imidazole derivatives provide a new afterglow luminescence mechanism. The work expands the range of afterglow luminescence frameworks to overcome: (i) a lack of new afterglow scaffolds; (ii) the dependence on initial external light activation; and (iii) aggregation‐caused quenching.
