Abstract The trifluoromethoxy moiety, an emerging fluorinated group, shows interesting properties for pharmaceutical and agrochemical applications. However, only few methods have been reported the direct introduction of this group on molecules with high efficiency, safety low cost. Indeed, most trifluoromethoxylation reagents are either expensive, hazardous or require preliminary synthesis before their use. Here we describe use 2,4‐dinitro‐1‐(trifluoromethoxy)benzene (DNTFB) as easy‐to‐handle, safe, commercially available cheap source trifluoromethoxide anion arynes.

Phenylseleno trifluoromethoxylation of alkenes

Beilstein Journal of Organic Chemistry, Год журнала: 2024, Номер 20, С. 2434 - 2441

Опубликована: Сен. 26, 2024

Trifluoromethoxylated molecules and selenylated compounds find a wide range of interesting applications, but separately. In order to combine the potential these two motifs propose new class compounds, we have developed an electrophilic phenylseleno trifluoromethoxylation alkenes, which leads β-selenylated trifluoromethoxylated or, upon subsequent reduction, ones.

The development of emerging fluorinated groups is an active field research in recent years. In particular, the fusion moieties with chalcogens has attracted considerable interest. This led to a strong demand for new efficient reagents perform various direct trifluoromethylchalcogenations. Herein, we present overview results obtained our laboratory Lyon, which actively contributed this quest during last 15 Le développement de groupes fluorés émergents est un domaine recherche très actif ces dernières années. En particulier, l'association groupements avec des chalcogènes suscité intérêt tout particulier. Cela induit une forte demande pour développer nouveaux réactifs efficaces permettant d'effectuer diverses trifluorométhylchalcogénations directes. Dans cet article, nous allons présenter aperçu principaux résultats notre laboratoire lyonnais, qui activement contribué à cette quête au cours
