Remarkably, the complex\n                    <jats:bold>Mn\u2010ph<\/jats:bold>\n                    with an aromatic imine bridge was found to be efficient in comparison to\n                    <jats:bold>Mn\u2010en<\/jats:bold>\n                    , leading to an excellent yield of \u03b1\u2010alkylated ketone with good selectivity under operationally convenient conditions. Interestingly, a wide range of aromatic, cyclic, and heterocyclic ketones are effectively alkylated under the optimized reaction conditions. Notably, the transformation proceeds via an environmentally benign and atom\u2010efficient pathway, generating water as the sole byproduct. The control experiments reveal the involvement of dehydrogenation of alcohols and hydrogen autotransfer (HA) pathway. These findings highlight the potential of Mn(II)\u2010salen complexes in catalytic HA processes, expanding their applications in sustainable C\u00a0\u2500\u00a0C bond formation strategies.\n                  <\/jats:p>","DOI":"10.1002\/chem.202501104","type":"journal-article","created":{"date-parts":[[2025,6,24]],"date-time":"2025-06-24T09:13:40Z","timestamp":1750756420000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["\u03b1\u2010Alkylation of Ketones Using Primary Alcohols: Unveiling the Role of Manganese\u2010Salen Complexes"],"prefix":"10.1002","volume":"31","author":[{"given":"Anjima T","family":"L","sequence":"first","affiliation":[{"name":"Main Group Organometallics Optoelectronic Materials and Catalysis Lab, Department of Chemistry National Institute of Technology  Calicut 673601 India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7875-9517","authenticated-orcid":false,"given":"Chinna Ayya Swamy","family":"P","sequence":"additional","affiliation":[{"name":"Main Group Organometallics Optoelectronic Materials and Catalysis Lab, Department of Chemistry National Institute of Technology  Calicut 673601 India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,2]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/adsc.202200474"},{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201507521"},{"key":"e_1_2_8_1_3","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.7b00340"},{"key":"e_1_2_8_1_4","doi-asserted-by":"publisher","DOI":"10.1021\/acscatal.8b02998"},{"key":"e_1_2_8_1_5","doi-asserted-by":"publisher","DOI":"10.1039\/D0DT03282D"},{"key":"e_1_2_8_1_6","doi-asserted-by":"publisher","DOI":"10.1002\/cctc.201601176"},{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.joc.9b00792"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200603794"},{"key":"e_1_2_8_2_3","doi-asserted-by":"publisher","DOI":"10.1021\/cr100280d"},{"key":"e_1_2_8_2_4","doi-asserted-by":"publisher","DOI":"10.1021\/acs.joc.1c00592"},{"key":"e_1_2_8_2_5","doi-asserted-by":"publisher","DOI":"10.1021\/cs5009656"},{"key":"e_1_2_8_2_6","doi-asserted-by":"publisher","DOI":"10.1021\/acs.organomet.2c00520"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201503247"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201403873"},{"key":"e_1_2_8_3_3","doi-asserted-by":"publisher","DOI":"10.1039\/C7CS00334J"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/cctc.201701241"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/cctc.202401744"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/cctc.202300542"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1021\/acsomega.2c03200"},{"key":"e_1_2_8_5_3","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2016.09.014"},{"key":"e_1_2_8_5_4","doi-asserted-by":"publisher","DOI":"10.1021\/acs.joc.8b00013"},{"key":"e_1_2_8_5_5","doi-asserted-by":"publisher","DOI":"10.1021\/acs.orglett.0c04098"},{"key":"e_1_2_8_5_6","doi-asserted-by":"publisher","DOI":"10.1021\/acscatal.6b01351"},{"key":"e_1_2_8_5_7","doi-asserted-by":"publisher","DOI":"10.1016\/j.tet.2017.03.022"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/cs400066q"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/jo502051d"},{"key":"e_1_2_8_6_3","doi-asserted-by":"publisher","DOI":"10.1021\/acs.organomet.7b00478"},{"key":"e_1_2_8_6_4","doi-asserted-by":"publisher","DOI":"10.1021\/cs4005375"},{"key":"e_1_2_8_6_5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jorganchem.2017.05.055"},{"key":"e_1_2_8_6_6","doi-asserted-by":"publisher","DOI":"10.1021\/acs.joc.8b00043"},{"key":"e_1_2_8_6_7","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetlet.2014.11.034"},{"key":"e_1_2_8_6_8","first-page":"55","volume":"240","author":"Cho C.","year":"2005","journal-title":"J.
