Reactions of Terminal Olefins With Iron Carbenes

Angewandte Chemie, EarlyView.
Iron carbenes react with terminal olefins and show productive metathesis or metathesis‐divergent pathways depending on the nature of the olefin. Reactions proceed through 2π + 2π cycloadditions to generate transient metallacyclobutane intermediates that undergo cycloreversion to generate the metathesis product or the metathesis‐divergent β‐hydride ...

Suppression of Peierls Instability in a Metal−Halide Porous Framework

Angewandte Chemie, EarlyView.
Peierls distortion in one‐dimensional Pt‐I chains is suppressed by confinement within the periodic electrostatic environment of a porous Cu–I framework. X‐ray crystallography shows equivalent Pt–I distances without bond alternation, and conductivity of the Pt‐I chains is greatly enhanced.

A Modular Synthesis of C5‐Sulfenyl Thiazoles via an Intermolecular Pummerer Rearrangement: An Underexplored Scaffold for Medicinal Chemistry

Angewandte Chemie, EarlyView.
Modular access to underexplored C5‐sulfenyl thiazoles via an intermolecular Pummerer rearrangement is reported. The methodology exhibits a broad functional group tolerance enabling the seamless design of trisubstituted thiazole cores bearing a sulfur handle for further elaboration.

Induction of Methuosis in Breast Cancer Stem Cells by a Cobalt(III) Complex Evokes Immunotherapeutic Response

Angewandte Chemie, EarlyView.
Cancer stem cells (CSCs) drive metastasis, relapse and resist conventional apoptosis‐inducing chemotherapies. We report a cobalt(III)‐cyclam complex with pyrene and diflunisal moieties that reduces the viability of breast CSCs at low micromolar concentrations.

TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

Angewandte Chemie, EarlyView.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...
