Asian Journal of Organic Chemistry, EarlyView.An interrupted Barton–Zard reaction/Friedel–Crafts alkylation telescoped reaction provides aryl‐substituted pyrrolo[3,4‐b] cores in moderate‐to‐good yields as mostly single diastereomers. The reaction is tolerant of a wide range of electron‐deficient indoles and (hetero)aromatic nucleophiles, offering a modular approach for the synthesis of multi ...

Photocontrolled Release of Urea Enables the Detection of Urea–Urease Intermediates by Cryo‐FTIR
Angewandte Chemie, EarlyView.Urease is a fast enzyme, presenting kcat of the order of 103–104 s−1. To enable the visualization of its mechanism we explored the technique of cryo‐FTIR. By means of using a ruthenium complex as a caged‐urea, upon light irradiation urea was released and we could see the coordination of the urea to the active site.

Asian Journal of Organic Chemistry, EarlyView.High‐valent Rh(IV) and Rh(V) species have been invoked to rationalize enhanced catalytic reactivity. This review examines evidence for both, emphasizing reactions proceeding through the Rh(III)/Rh(IV)/Rh(II) cycle. While Rh(V) intermediates are computationally supported, experimental evidence is limited; Rh(IV) species are supported by both theory and ...

Zwitterionic Heavier Pnictinidenes in Redox Catalysis
Angewandte Chemie, EarlyView.Zwitterionic pnictinidenes: A new class of zwitterionic heavier pnictogen species stabilized by bis(N‐heterocyclic carbene)borate ligands is reported, enabling the isolation of Sb and Bi in multiple oxidation states. These thoroughly characterized systems exhibit cationic character and engage in redox catalysis, facilitating catalytic ...
