The regioselective H\/D exchange in the methyl groups detected on H\u2010BEA can be rationalized in terms of the mechanism of indirect exchange, which involves protonation of the intermediate olefin and further hydride abstraction from the other alkane molecule by the formed carbenium ion. Loading of Zn species in the zeolite results in a decrease of the rate and an increase of the activation energy of the exchange. The loaded Zn species provide the tuning effect on the reaction occurrence, changing the mechanism from the indirect one to the mechanism of the direct exchange.<\/jats:p>","DOI":"10.1002\/chem.202202962","type":"journal-article","created":{"date-parts":[[2022,10,31]],"date-time":"2022-10-31T05:42:30Z","timestamp":1667194950000},"update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Tuning the Mechanism of H\/D Exchange for Isobutane on H\u2010BEA by Loading Zn Species in Zeolite"],"prefix":"10.1002","volume":"29","author":[{"ORCID":"http:\/\/orcid.org\/0000-0001-7358-3364","authenticated-orcid":false,"given":"Sergei S.","family":"Arzumanov","sequence":"first","affiliation":[{"name":"Boreskov Institute of Catalysis Siberian Branch of the Russian Academy of Sciences Prospekt Akademika Lavrentieva 5 Novosibirsk 630090 Russia"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-2811-3635","authenticated-orcid":false,"given":"Anton A.","family":"Gabrienko","sequence":"additional","affiliation":[{"name":"Boreskov Institute of Catalysis Siberian Branch of the Russian Academy of Sciences Prospekt Akademika Lavrentieva 5 Novosibirsk 630090 Russia"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-1814-3486","authenticated-orcid":false,"given":"Dieter","family":"Freude","sequence":"additional","affiliation":[{"name":"Universit\u00e4t Leipzig Fakult\u00e4t f\u00fcr Physik und Geowissenschaften Linn\u00e9str. 5 04103 Leipzig Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-0140-6964","authenticated-orcid":false,"given":"J\u00fcrgen","family":"Haase","sequence":"additional","affiliation":[{"name":"Universit\u00e4t Leipzig Fakult\u00e4t f\u00fcr Physik und Geowissenschaften Linn\u00e9str. 5 04103 Leipzig Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-2754-5273","authenticated-orcid":false,"given":"Alexander G.","family":"Stepanov","sequence":"additional","affiliation":[{"name":"Boreskov Institute of Catalysis Siberian Branch of the Russian Academy of Sciences Prospekt Akademika Lavrentieva 5 Novosibirsk 630090 Russia"}]}],"member":"311","published-online":{"date-parts":[[2022,12,5]]},"reference":[{"key":"e_1_2_9_1_1","unstructured":"\u00a0"},{"key":"e_1_2_9_2_2","volume-title":"Hydrocarbon Chemistry",
