This way MeClAl\u2010, Cl<jats:sub>2<\/jats:sub>Al\u2010 and (C<jats:sub>6<\/jats:sub>F<jats:sub>5<\/jats:sub>)<jats:sub>2<\/jats:sub>Al\u2010 moieties could be introduced and the resulting FLPs are stabilized by a further equivalent of the alane precursors. In contact with the FLPs CO<jats:sub>2<\/jats:sub> is bound via the C atom at the phosphane functions and the two O atoms at the Al centers. The residues at the latter determine the binding strength. Hence, in case of MeClAl CO<jats:sub>2<\/jats:sub> capture occurs at higher pressure and under ambient conditions CO<jats:sub>2<\/jats:sub> is released again, while for Cl<jats:sub>2<\/jats:sub>Al and (C<jats:sub>6<\/jats:sub>F<jats:sub>5<\/jats:sub>)<jats:sub>2<\/jats:sub>Al CO<jats:sub>2<\/jats:sub> binding becomes irreversible. The results of DFT calculations rationalize these findings by the high thermodynamic stabilization in case of more electronegative residues, which concomitantly lead to higher barriers, and in case of (C<jats:sub>6<\/jats:sub>F<jats:sub>5<\/jats:sub>)<jats:sub>2<\/jats:sub>Al further stabilization is achieved through a low reorganization energy.<\/jats:p>","DOI":"10.1002\/chem.202200404","type":"journal-article","created":{"date-parts":[[2022,2,25]],"date-time":"2022-02-25T08:35:11Z","timestamp":1645778111000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Synthesis of Intramolecular P\/Al\u2010Based Frustrated Lewis Pairs via Aluminum\u2010Tin\u2010Exchange and their Reactivity toward CO<sub>2<\/sub>"],"prefix":"10.1002","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0278-0181","authenticated-orcid":false,"given":"Patrick","family":"Federmann","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Chemie Humboldt-Universit\u00e4t zu Berlin  Brook-Taylor-Stra\u00dfe 2 12489 Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9135-8125","authenticated-orcid":false,"given":"Robert","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Chemie Theoretische Chemie\/Quantenchemie Sekr.
