Here, we report an iron-catalyzed decarboxylative carbonyl alkylative amination of aldehydes, amines, and carboxylic acids in HFIP under mild light irradiation at room temperature, with no additional additives and only CO\n                    <jats:sub>2<\/jats:sub>\n                    and H\n                    <jats:sub>2<\/jats:sub>\n                    O as environmentally benign by-products. This protocol exhibits exceptional compatibility with sterically hindered substrates and a broad range of functional groups, enabling late-stage drug modification, hybrid drug conjugation, and pharmaceutical analog synthesis. EPR spectroscopy directly detected carbon- and nitrogen-centered radicals, corroborating the proposed mechanistic pathway where alkyl radicals add to in situ\u2013generated iminium ions to form aminium radical cations. HFIP plays a critical role by accelerating aldehyde-amine condensation, shifting tautomeric equilibria toward reactive iminium ions, and lowering the activation barrier for the key radical addition step.\n                  <\/jats:p>","DOI":"10.1126\/sciadv.aeg1452","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T17:59:33Z","timestamp":1782496773000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":1,"title":["Decarboxylative carbonyl alkylative amination: A general and practical strategy for aliphatic amine synthesis"],"prefix":"10.1126","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-7497-910X","authenticated-orcid":true,"given":"Ling-Zhi","family":"Meng","sequence":"first","affiliation":[{"name":"School of Science, Hebei Provincial Key Laboratory of Photoelectric Control on Surface and Interface, Hebei University of Science and Technology, Shijiazhuang 050022, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Tong","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Science, Hebei Provincial Key Laboratory of Photoelectric Control on Surface and Interface, Hebei University of Science and Technology, Shijiazhuang 050022, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao-Dan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Science, Hebei Provincial Key Laboratory of Photoelectric Control on Surface and Interface, Hebei University of Science and Technology, Shijiazhuang 050022, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai-Yue","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Science, Hebei Provincial Key Laboratory of Photoelectric Control on Surface and Interface, Hebei University of Science and Technology, Shijiazhuang 050022, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Di-Di","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Science, Hebei Provincial Key Laboratory of Photoelectric Control on Surface and Interface, Hebei University of Science and Technology, Shijiazhuang 050022, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao-Yu","family":"Chen","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Biomass Chemistry, CAS Key Laboratory of Urban Pollutant Conversion, University of Science and Technology of China, Hefei 230026, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-3141-167X","authenticated-orcid":true,"given":"Ying-Zhuang","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Science, Hebei Provincial Key Laboratory of Photoelectric Control on Surface and Interface, Hebei University of Science and Technology, Shijiazhuang 050022, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6487-9339","authenticated-orcid":true,"given":"Wei","family":"Su","sequence":"additional","affiliation":[{"name":"School of Science, Hebei Provincial Key Laboratory of Photoelectric Control on Surface and Interface, Hebei University of Science and Technology, Shijiazhuang 050022, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5484-8531","authenticated-orcid":true,"given":"Tian-Jun","family":"Gong","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Biomass Chemistry, CAS Key Laboratory of Urban Pollutant Conversion, University of Science and Technology of China, Hefei 230026, China."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"221","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1021\/jm901241e"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1021\/jm200187y"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jafc.0c01909"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41557-018-0021-z"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/nchembio0606-284"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1039\/C5NP00096C"},{"key":"e_1_3_2_8_2","doi-asserted-by":"crossref","unstructured":"S.-k.
