Visible‐Light‐Induced Carbon–Hydrogen Phosphonylation of Conjugated Polymers via Electron Donor–Acceptor Complex Activation

Angewandte Chemie, EarlyView.
Electron donor–acceptor (EDA) complex activation enabled the efficient transformation of conjugated polymers. Compared with the small‐molecule model compound, the polymers reacted more efficiently, achieving quantitative conversion of PFO. This result demonstrates a new platform for incorporating conjugated polymers into EDA‐mediated photochemical ...

Light‐Driven Out‐of‐Equilibrium Helicity Control in a Diarylethene–Helicene Photosystem

Angewandte Chemie, EarlyView.
Distinct energy landscapes of different helicities in the open and closed states of a diarylethene–helicene photoswitch enable a light‐driven energy ratchet. Helix inversion occurs selectively in the closed form, and the resulting helicity is transferred and kinetically trapped upon ring opening, generating a persistent out‐of‐equilibrium chiral state ...

Deprotektive Alkylierung: Eine Plattform zur Umsetzung von Alkoholen zu Aminen mittels Nonafluormesitylensulfonamiden

Angewandte Chemie, EarlyView.
Die direkte Umwandlung von Alkoholen in tertiäre oder sekundäre Amine in einem Reaktionsschritt unter Verwendung von Nms‐Amiden wird beschrieben. Die Transformation zeichnet sich durch eine breite Toleranz gegenüber verschiedenen funktionellen Gruppen und eine hohe Stereospezifität aus, was ihre Eignung für die Synthese isotopenmarkierter Arzneimittel ...

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

Angewandte Chemie, EarlyView.
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.

Record Dissymmetry in Vibrational Optical Activity: Combining Vibronic Coupling and Aggregation in Cobalt(II) Camphorate Complexes

Angewandte Chemie, EarlyView.
The cobalt(II) bis(trifluoroacetylcamphorate) scaffold exhibits versatile coordination chemistry with solvent‐driven ligand exchange and geometrical rearrangements, associated with unique chiroptical properties. Microcrystalline suspension of [Co(tfc)2(CH3CN)2] revealed the largest VCD dissymmetry factor ever reported (g ≈ 0.2 at 1600 cm−1), arising ...

Intramolecular Nickel‐Catalyzed Reductive Coupling: Enantioselective Synthesis of Tetrahydroisoquinolines and Related Heterocycles

Angewandte Chemie, EarlyView.
The successful extension of the nickel‐catalyzed asymmetric coupling of polarized 1,3‐dienes with aldehydes to an intramolecular setting opens an efficient new entry into hydroxylated N‐heterocyclic compounds, most notably valuable tetrahydroisoquinolines.
