T‐Shaped Stibenium(III) Cation: Hydrostibination Without Sb─H Bond

Angewandte Chemie, EarlyView.
A cationic, structurally constrained stibenium platform mediates anti‐Markovnikov hydrostibination of alkenes via element–ligand cooperativity (ELC), thereby bypassing the need for weak Sb─H bonds. ABSTRACT The hydrostibination of alkenes represents a largely underdeveloped transformation, owing to the intrinsic lability of the required Sb─H reagents ...

Unraveling Terminal Cobalt–Antimony Double Bond: Breaking New Ground in Heavy Pnictogen Multiple Bonds

Angewandte Chemie, EarlyView.
N‐heterocyclic carbenes (NHCs) function as “molecular scissors,” cleaving otherwise inert Sb═Sb bonds in distibenes to generate monomeric, zwitterionic stibinide species. These intermediates act as efficient stibinidene transfer reagents, granting access to a rare terminal cobalt–stibinidene complex.

Tuning the Mechanical Properties of Crosslinked Copolymers via Sequence and Solvent‐Selective Swelling for Vat Photopolymerization

Angewandte Chemie, EarlyView.
Polymer sequence and solvent selectivity independently modulate pendant‐vinyl accessibility during photocuring, trapping different topologies in CLIP and controlling mechanical properties. ABSTRACT Block copolymers (BCPs) offer distinct advantages for vat photopolymerization by enabling mechanically programmable network structures through microphase ...

Water, Alcohols, Amines, and Amides as Formal Hydrogen‐Atom‐Transfer Reagents Through Activation With Redox‐Active Lewis Acids

Angewandte Chemie, EarlyView.
Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.

Borylcyclopropanes: Synthetic Strategies and Applications

Angewandte Chemie, EarlyView.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...
