FON: An Innovative Fluorinated Group via Hydroetherification-Type Reactivity.

An efficient strategy for preparing the novel -difluoroalkylhydroxylamine fluorinated functional group, coined FON, is reported. This analogue of medicinally important β-phenethyl ether scaffolds in uniting -difluoro and N-O moieties is synthesized in one step via chemo- and regioselectivity metal-free hydroetherification-type additions. As shown, this unique mode of reactivity is realized for a diverse substrate scope and applied to gram-scale synthesis and site-selective deuterium incorporation.

Streamlining Fluoroalkenyl Arene Synthesis Illuminated with Mechanistic Insights.

Fluorinated compounds are a staple of modern-day chemical innovation, and efficient strategies for their synthesis are highly valuable. In this chemical space, fluoroalkenes continue to be the object of much interest across diverse fields, including drug development and pharmaceuticals with active roles as bioisosteres. Herein, in expanding chemists' synthetic toolbox for constructing valuable organofluorine compounds, we report a "pipeline" strategy for the synthesis of fluorinated olefins, .
