EnT-Mediated N-S Bond Homolysis of a Bifunctional Reagent Leading to Aliphatic Sulfonyl Fluorides.

Journal of the American Chemical Society, 2023
Sulfur(VI) fluoride exchange (SuFEx) gives rise to a plethora of high-valent sulfur linkages; however, the availability of (aliphatic) sulfonyl fluoride manifolds lag behind, owing to the limited sources of introducing the SO2F moiety via a classical two-

Acyl Fluorides in Late‐Transition‐Metal Catalysis

Angewandte Chemie - International Edition, 2020
In this review, we summarize the current state-of-the-art regarding late transition-metal-catalyzed reactions of acyl fluorides, including their synthesis and transformations. In organic reactions, the relationship between stability and reactivity of the

Magnesiation of Aryl Fluorides Catalyzed by a Rhodium-Aluminum Complex.

Journal of the American Chemical Society, 2020
We report the magnesiation of aryl fluorides cata-lyzed by a Al-Rh heterobimetallic complex. We show that the complex is highly reactive to cleave the C-F bonds across the polarized Al-Rh bond under mild conditions. The reaction allows the use of an easy-

Fluoride and flouridation

Social Science & Medicine, 1988
To date, many of the ways of controlling tooth decay involve the use of fluorides. Either systemically via fluoridated water and tablets, or, topically, with fluoride-containing toothpaste and mouthrinses. There is now evidence that the prevalence of dental caries is declining in communities with unfluoridated water, as well as in those with ...

Deoxyfluorination with Sulfonyl Fluorides: Navigating Reaction Space with Machine Learning.

Journal of the American Chemical Society, 2018
Through fine-tuning of reagent and base structure, sulfonyl fluorides can efficiently fluorinate diverse classes of alcohols. We show that machine learning can map the intricate reaction landscape and enable accurate prediction of high-yielding ...
