Photoelectrochemical Iron(III) Catalysis for Late‐Stage C–H Fluoroalkylations
Angewandte Chemie International Edition, Accepted Article.Chemo‐ and site‐selective functionalization of complex molecules poses a fundamental challenge. In this regard, the synergetic combination of photoexcitation with electron transfer by anodic oxidation bears unique potential for novel reaction manifolds that go beyond individual photo‐ or electrochemistry.[1‐3] Herein, we introduce a resource‐economic ...

Titanium‐Mediated Rearrangement of Bis(alkynyl)boranes: B–C Activation vs C–H Activation
Angewandte Chemie International Edition, Accepted Article.Reactions between Rosenthal’s titanocene (Cp2Ti) and decamethyltitanocene (Cp*2Ti) synthons with various bis(alkynyl)boranes were investigated. A series of titanium‐fused boracyclobutenes were obtained through the reaction of the Cp*2Ti synthon with (Me3Si)2NB(CCR)2 or PhB(CCPh)2.
