They were used for transfer hydrogenations to aldehydes, ketones, imines as well as electron\u2010poor alkene\/alkyne moieties. The amine\u2010borane Lewis\u2010paired oligomers and the congested bis(amine\u2010borane)s provided the highest yields. This was likely helped by facilitated dissociation (oligomers) or H\u2010bond assistance. In the case of the oligomers, the second equivalent of H<jats:sub>2<\/jats:sub> present was also engaged in the reaction. Solid\u2010state NMR characterization provides evidence that the boron\u2010containing materials obtained after transfer dehydrogenation are highly similar to those obtained from thermal dehydrogenation. The oligomers bridge the gap between simple amine\u2010borane molecular reductants and the poly\u2010amine\u2010boranes and provide a full picture of the reactivity changes at the different scales.<\/jats:p>","DOI":"10.1002\/chem.202300145","type":"journal-article","created":{"date-parts":[[2023,10,10]],"date-time":"2023-10-10T04:47:00Z","timestamp":1696913220000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Catalyst\u2010Free Transfer Hydrogenation from Amine\u2010Borane Small Oligomers"],"prefix":"10.1002","volume":"30","author":[{"given":"Louis","family":"Le Moigne","sequence":"first","affiliation":[{"name":"Univ Lyon Universit\u00e9 Claude Bernard Lyon 1 CNRS CNES ArianeGroup LHCEP UMR 5278  B\u00e2t.
