The homologation of alkenes, though important, remains challenging due to the difficulty of (CH\n                    <jats:sub>2<\/jats:sub>\n                    )\n                    <jats:sub>n<\/jats:sub>\n                    insertion into the main carbon chain of alkenes compared to chains containing other polar functional groups. Here, we report the homologation of both terminal and internal alkenes by using acetylene as a cheap and abundant C\n                    <jats:sub>2<\/jats:sub>\n                    feedstock. The process involves an in\u2010situ transformation of alkenes into boranes and then into elongated alkenes, during which direct (CH\n                    <jats:sub>2<\/jats:sub>\n                    )\n                    <jats:sub>n<\/jats:sub>\n                    insertion is avoided. The reaction can be carried out iteratively to achieve up to a 12\u2010carbon elongation.\n                  <\/jats:p>","DOI":"10.1002\/anie.202425169","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T17:06:04Z","timestamp":1741712764000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Homologation of Alkenes Using Acetylene as a C\n                    <sub>2<\/sub>\n                    Feedstock"],"prefix":"10.1002","volume":"64","author":[{"given":"Tairan","family":"Cheng","sequence":"first","affiliation":[{"name":"Key Laboratory of Functional Molecular Engineering of Guangdong Province School of Chemistry and Chemical Engineering South China University of Technology  Guangzhou 510640 P.R.
