摘要

Site-selective fluorination of aliphatic C–H bonds remains synthetically challenging. While directed C–H fluorination represents the most promising approach, the limited work conducted to date has enabled just a few functional groups as the arbiters of direction. Leveraging insights gained from both computations and experimentation, we enabled the use of the ubiquitous amine functional group as a handle for the directed C–H fluorination of Csp3–H bonds. By converting primary amines to adamantoyl-based fluoroamides, site-selective C–H fluorination proceeds under the influence of a simple iron catalyst in 20 minutes. Computational studies revealed a unique reaction coordinate for the catalytic process and offer an explanation for the high site selectivity.

Our journal has a wide-ranging scope which covers the full breadth of the chemical sciences. The research we publish contains the sorts of novel ideas, challenging questions and progressive thinking that bring undiscovered breakthroughs within reach. Your paper could focus on a single area, or cross many. It could be beyond the accepted bounds of the chemical sciences. It might address an immediate challenge, contribute to a future breakthrough or be wholly conceptual. We’re a team from every field of the chemical sciences, and know from experience that breakthroughs that drive the solutions to global challenges can come from anywhere, at any time. You could even start an entirely new area of research. Too bold? Too progressive? No such thing
