The energy and geometry results demonstrate that the transition state (TS) structure for the LiAlH4-formaldehyde complex is reactant-like, while the structure generated by LiBH4 has a product-like geometry, consistent with the Hammond postulate. From a charge density analysis, we also found that both complexes undergo the same essential hydride transfer mechanism, which consists of: (1) single electron transfer to the carbonyl carbon, (2) formation of a bridge bond (X-H-C; X=Al or B) and (3) hydrogen transfer driven by electron transfer. Subsequently, in a fourth step, a single electron flows through the X-H-C bond during transfer of the hydrogen, such that hydrogen atom or proton-coupled electron transfer occurs. In both systems, the presence of tetrahydrofuran as a solvent affects the structure and energy values during the reaction, but not the charge transfer characteristics. We propose that the rate-determining steps during hydride transfer when employing LiAlH4 and LiBH4 are one electron transfer to the carbonyl carbon and B-H bond dissociation, respectively. © 2015 Elsevier B.V.","subitem_description_type":"Abstract"}]},"item_4_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Embargo Period 24 months","subitem_description_type":"Other"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学ナノマテリアル研究所 / 金沢大学理工研究域数物科学系","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00010817","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.comptc.2015.12.014","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.elsevier.com/locate/issn/2210271X","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © Elsevier (CC-BY NC ND)"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA12611200","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2210-271X","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hori, Yuta"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ida, Tomonori"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Mizuno, Motohiro"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-16"}],"displaytype":"detail","filename":"SC-PR-HORI-Y-86.pdf","filesize":[{"value":"666.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-HORI-Y-86.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10830/files/SC-PR-HORI-Y-86.pdf"},"version_id":"00f2c163-52f9-4096-9415-bb9268b7ccb1"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A comparative theoretical study of the hydride transfer mechanisms during LiAlH4 and LiBH4 reductions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A comparative theoretical study of the hydride transfer mechanisms during LiAlH4 and LiBH4 reductions"}]},"item_type_id":"4","owner":"3","path":["4188"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-05"},"publish_date":"2017-12-05","publish_status":"0","recid":"10830","relation_version_is_last":true,"title":["A comparative theoretical study of the hydride transfer mechanisms during LiAlH4 and LiBH4 reductions"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T09:50:53.271761+00:00"}
