Piano‐Stool Rhodium(V) and Rhodium(IV) Intermediates in C─H Functionalization and B─H Functionalization: Mechanistic Insights and Emerging Reactivity

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 ...

Wacker Oxidation of Trisubstituted Alkenes: Pd(II)‐Catalyzed Oxidative Ring Expansion of Exocyclic α,β‐Unsaturated Carbonyl to 2‐Fluoro‐1,3‐Dicarbonyl Compounds

Angewandte Chemie, EarlyView.
First examples of Pd(II)‐catalyzed Wacker oxidation of trisubstituted alkenes, coupled with electrophilic fluorination, enable a one‐carbon ring expansion of exocyclic α,β‐unsaturated carbonyls to 2‐fluoro‐2‐acyl‐cycloalkanones. Abstract The Wacker oxidation is a powerful synthetic method widely employed for the transformation of monosubstituted ...

Brassinin from Brassica campestris L. inhibits colorectal cancer by inducing p62/NRF2/GPX4‐regulated ferroptosis

Animal Models and Experimental Medicine, EarlyView.
BSN suppresses the cell viability of colorectal cancer by inducing GPX4‐regulated ferroptosis. BSN may bind to NRF2 protein to inactivate the NRF2 signaling, inhibiting the expression of p62 and HO‐1. Abstract Background Indole phytoalexins, plant‐derived compounds present in cruciferous vegetables, have demonstrated anticancer properties.

Unveiling an Alternative Mechanism for Lewis Basic Selenium as a C─H Hydrogen Bond Catalyst and Its Application in the Halogenation of Arenes

Angewandte Chemie, EarlyView.
This work demonstrates an unconventional mechanism in Lewis basic selenium‐catalyzed electrophilic halogenation, where in situ oxidation of selenourea by the halogen source generates hypervalent Se‐imidazolium species. These intermediates function as hydrogen‐bond catalysts to activate N‐haloamide reagents, enabling efficient and mild halogenation of ...
