2025-05-27T12:23:40Z urn:hdl:10259/10503 Halogen Promoted Desulfurative Cleavage of Cyclopropylmethyl Thioethers and Amination of the Formed Cyclopropylcarbinyl Cations Marín Díaz, Pablo Martínez Núñez, Clara Sanz Díez, Roberto Suárez Pantiga, Samuel Cyclopropylmethyl sulfides react with N-fluorosulfonimide (NFSI) or molecular iodine, enabling C−S cleavage to generate cyclopropylcarbinyl cations, which evolve through cyclopropane ring-opening reactions into homoallyl cations suitable to react with nucleophiles present in the reaction media. This desulfurative cleavage of cyclopropylmethyl thioethers under non-acidic conditions facilitates homoallylation of N-based nucleophiles such as alkyl or aryl amines as well as sulfonimides through a one-pot protocol in one or two steps depending on the nucleophile. The reaction is initiated by a halogen-sulfur bond that causes C−S bond cleavage. Moreover, the reaction with iodine proceeds through homoallyl iodide intermediates. 2025-05-27T12:23:40Z 2025-05-27T12:23:40Z 2024-03 info:eu-repo/semantics/article 1434-193X http://hdl.handle.net/10259/10503 10.1002/ejoc.202400147 1099-0690 eng European Journal of Organic Chemistry. 2024, V. 27, n. 20, p. e202400147 https://doi.org/10.1002/ejoc.202400147 http://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess Atribución-NoComercial 4.0 Internacional Wiley
