Arylative Ring Expansion of 3-Vinylazetidin-3-Ols and 3-Vinyloxetan-3-Ols to Dihydrofurans by Dual Palladium and Acid Catalysis

In contrast to the well-studied 1-vinylcyclobutanols, the reactivity of 3-vinylazetidin-3-ols 1 and 3-vinyloxetan-3-ols 2 under transition metal catalysis remains largely unexplored. We report herein their unique reactivity under dual palladium and acid ca ...

Origin of metallic-like behavior in disordered carbon nano-onions

Oleg Yazyev, Kristians Cernevics

Carbon nano-onions are a class of nanomaterials that can exhibit long electron spin relaxation times at room temperature and thus hold promise as potential building blocks for spintronics and quantum information processing devices. Despite first being synt ...

Spatial Charge Separation as the Origin of Anomalous Stark Effect in Fluorous 2D Hybrid Perovskites

Mohammad Khaja Nazeeruddin, Jacques-Edouard Moser, Giulia Grancini, Valentin Ianis Emmanuel Queloz, Inés Garcia Benito, Marine Eva Fedora Bouduban, Alexander Fedorovskiy

2D hybrid perovskites (2DP) are versatile materials, whose electronic and optical properties can be tuned through the nature of the organic cations (even when those are seemingly electronically inert). Here, it is demonstrated that fluorination of the orga ...

Copper-catalyzed remote C(sp3)–H azidation and oxidative trifluoromethylation of benzohydrazides

Qian Wang, Jieping Zhu, Xu Bao

The Hofmann-Löffler-Freytag (HLF) reaction is a prototypical example of radical-based remote functionalization of unactivated C(sp3)–H bond. While 1,5-hydrogen atom transfer (1,5-HAT) of the amidyl radical is thermodynamically favorable and is well-establi ...
