Abstract

Intramolecular amination of remote aliphatic C-H bonds via hydrogen-atom transfer reactions has become a powerful tool for accessing saturated nitrogen-containing heterocycles. However, the formation of six-membered rings or oxa-heterocycles remains a formidable challenge for Hofmann-L & ouml;ffler-Freytag reactions. Here we show how by simply combining bench-stable (bis(trifluoroacetoxy)iodo)benzene and hexafluoroisopropanol (HFIP) we can switch from the well-established Hofmann-L & ouml;ffler-Freytag mechanism to a different versatile reaction pathway that enables selective C(sp3)-H bond functionalization. We have exploited the facile formation of radical cations via single-electron transfer, in the presence or absence of light, to synthesize pyrrolidines and piperidines, including drug-type molecules, along with O-heterocycles. Experimental and computational mechanistic studies support two distinct mechanistic pathways, depending on the electron density of the substrate, in which the HFIP plays a multifunctional role. Saturated heterocycles are prevalent motifs in organic synthesis but their synthesis still presents persistent challenges. Now, a hypervalent iodine(III)-mediated selective intramolecular C(sp3)-H functionalization, facilitated by hexafluoroisopropanol, is reported, which via single-electron transfer provides access to pyrrolidines, piperidines and O-heterocycles in the presence or absence of light.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-03-15:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 22.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 22 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 37.
  • The number of mentions on the social network X (formerly Twitter): 24 (Altmetric).
  • The number of mentions in news outlets: 3 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: http://hdl.handle.net/20.500.11797/imarina9378022
Continuing with the social impact of the work, it is important to emphasize that, due to its content, it can be assigned to the area of interest of ODS 6 - Clean water and sanitation, with a probability of 62% according to the mBERT algorithm developed by Aurora University.
