Synthesis, Isolation, and Reactivity of a Phosphinidene Telluride

Angewandte Chemie, EarlyView.
We describe the synthesis and isolation of a phosphinidene telluride. This species acts as a versatile phosphinidene transfer reagent accompanied by the extrusion of elemental tellurium. Abstract The synthesis and isolation of a phosphorus(III) telluride is reported.

Controlled Dual Activation of Rhenium(I) Photosensitizers and Profluorophores/Prodrugs via a Dissociative Bioorthogonal Tetrazine–Isonitrile Reaction

Angewandte Chemie, EarlyView.
Rhenium(I) tetrazylmethyl complexes serve as phosphorogenic bioorthogonal reagents, releasing luminescent and photocytotoxic rhenium(I) 3‐hydroxypyridine complexes and functional payloads upon reaction with 3‐isocyanopropyl derivatives. Their selective lysosomal accumulation in cancer cells and enhanced singlet oxygen photosensitization in acidic ...

Silicon‐Based Azo Compound‐Mediated CO Activation and N2 Release

Angewandte Chemie, EarlyView.
A rare silicon(IV)‐based azo compound featuring a Si─N═N─Si linkage was synthesized via the direct reaction of an organoazide with a silaiminyl–silylene precursor. This compound undergoes an unusual CO activation process, resulting in N2 release and complete cleavage of the C≡O bond, forming a Si(II)/Si(IV) product bridged by an oxygen atom and an ...

Total Synthesis of Calyciphylline F

Angewandte Chemie, EarlyView.
The final challenge in the total synthesis of the caged polycyclic Daphniphyllum alkaloids was the Calyciphylline D‐type alkaloid, featuring a strained 8‐azatricyclo[4.2.1.04,8]nonane ring system. Presented herein is the total synthesis of calyciphylline F, a member of the calyciphylline D‐type alkaloid family, by an intramolecular [4 + 3 ...
