Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin

Angewandte Chemie, EarlyView.
Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.

Atroposelective Suzuki–Miyaura Coupling to Form 2‐Amino‐2′‐Hydroxybiphenyls Enabled by sRuPhos

Angewandte Chemie, EarlyView.
We report a new chiral phosphine ligand, sRuPhos, which permits the highly enantioselective Suzuki–Miyaura coupling of ortho‐aniline and ortho‐phenol building blocks. This results in 2‐amino‐2′‐hydroxybiphenyls with very high enantiomeric excesses, products that will have application in pharmaceutical synthesis and ligand design for catalysis ...

Synthesis and Characterization of Unusual S=1 Fe(0)‐Silyl Complexes Supported by Styrene Ligands

Angewandte Chemie, EarlyView.
Despite the long‐standing importance of iron‐silicon bonds as related to catalysis, high‐spin Fe(0)‐silyl complexes remain a historical synthetic challenge in the field. Herein, we report the first series of high‐spin S = 1, styrene‐stabilized Fe(0)‐silyl complexes followed by extensive characterization via Mössbauer spectroscopy, single crystal X‐ray ...

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications

Angewandte Chemie, EarlyView.
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...
