Iron‐Photocatalyzed C(sp3)–H Phosphonylation of Alkanes
Angewandte Chemie, EarlyView.Alkyl phosphonates are valuable motifs that can be prepared by phosphonylations of various common functional groups. However, direct phosphonylations of C(sp3)–H bonds are limited to activated positions. Herein, we report an iron‐photocatalyzed phosphonylation of unactivated C(sp3)–H bonds using a novel phosphite radical trap, which is equipped with an

Heavier Alkyne‐Ni0 Complexes, [R2E2·Ni] (E = Sn, Pb), Exhibiting σ‐Complex Character
Angewandte Chemie, EarlyView.Using a reductive group elimination strategy, heavier alkyne (LEEL; E = Sn, Pb) complexes of Ni0 are accessed. In contrast to classical alkyne coordination, these systems are best described as σ‐complexes, driven by ligand‐induced constraints and the established poor π‐bonding in heavier alkyne analogues.

Potassium‐Ligand Cooperation Facilitated Chemical Bond Activation and Catalytic Hydrogenation
Angewandte Chemie, EarlyView.A new strategy for alkali metal‐mediated catalysis based on metal–ligand cooperation (MLC) is presented. Potassium pincer complexes exhibit remarkable reactivity toward a range of molecules via an unprecedented potassium–ligand cooperative mechanism. This reactivity enables potassium‐catalyzed hydrogenation, providing efficient reduction of ketones and

3D‐Printable Nanoporous Thermosets via Disulfide‐Based Polymerization‐Induced Microphase Separation
Angewandte Chemie, EarlyView.α‐Lipoic acid‐derived degradable macro‐chain transfer agents (macroCTAs) with tunable hydrophilicity drive polymerization‐induced microphase separation (PIMS) in photocurable resins. Selective etching via disulfide cleavage then generates interconnected nanoporous thermosets, and compatibility with liquid‐crystal display (LCD) 3D printing enables the ...
