Reaction of copper(I) complexes ([Cu(L)]^+ generated bis(μ-oxo)dicopper(III) complexes, which showed reversible conversion to copper(I) complexes by bubbling of N_2. Furthermore, it was also found that bis(μ-oxo)dicopper(III) complexes have monooxygenase activity for the supporting ligands. Reactivity can be modulated by stereochemical electronic effect of the supporting ligands\n<Reaction intermediates of nickel complexes having a variety of dioxygen active species formed by the reaction with H_2O_2> Reaction of a bis(μ-hydroxo)Ni(II)_2 having a series of tetradentate tripodal ligands having methyl substituents with H_2O_2 at low temperature resulted in a successive formation a bis(μ-oxo)Ni(III)_2 a bis(μ-superoxo)Ni(II)_2, and a bis(μ-alkylperoxo)Ni(II)_2 complexes as the intermediates for the conversion of a methyl substituent of ligands to carboxylate and alkoxide ligands\n<Reversible O-O bond cleavage and formation of a peroxo group of an iron(III) complex having a peroxycarbonate> A peroxcarbonate iron(III) complex ([Fe(qn)_2(O_2C(O)O)]^-(1)) was synthesized. The complex is stable at -35℃ in acetonitrile, whereas it decomposes at 20℃. Decomposition of an ^<18>O-labeled [Fe(qn)_2(^<18>O-^<18>OC(O)O)]^-complex (1-^<18>O-^<18>O) at 20℃ in acetonitrile was investigated by resonace Raman and ESI-MS spectroscopies. They revealed that the ^<18>O-^<18>O of the peroxocarboante ligand is converted through ^<16>O-^<18>OC(O)O and ^<18>O-^<16>OC(O)O to ^<16>O-^<16>OC(O)O during thermal decomposition. This is the first example which showed reversible O-O bond cleavage and formation for iron complexes.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:11228202, 研究期間(年度):1999-2002","subitem_description_type":"Other"},{"subitem_description":"出典：「二核遷移金属錯体による酸素活性化機構の解明」研究成果報告書　課題番号11228202\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所））\n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-11228202/112282022003kenkyu_seika_hokoku_gaiyo/)を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00060747","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/search/?kw=20091390"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=20091390","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-11228202/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-11228202/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-11228202/112282022003kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-11228202/112282022003kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_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":"鈴木, 正樹"}],"nameIdentifiers":[{"nameIdentifier":"54","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20091390","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20091390"},{"nameIdentifier":"20091390","nameIdentifierScheme":"研究者番号","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000020091390"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-10-22"}],"displaytype":"detail","filename":"SC-PR-SUZUKI-M-kaken 2005-3p.pdf","filesize":[{"value":"133.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-SUZUKI-M-kaken 2005-3p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/54471/files/SC-PR-SUZUKI-M-kaken 2005-3p.pdf"},"version_id":"6528adb6-80a6-43c1-99f8-9e83f9453181"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"二核遷移金属錯体による酸素活性化機構の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"二核遷移金属錯体による酸素活性化機構の解明"},{"subitem_title":"Investigations of dioxygen activation mechanisms by dimetal complexes","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2830"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-10-22"},"publish_date":"2021-10-22","publish_status":"0","recid":"54471","relation_version_is_last":true,"title":["二核遷移金属錯体による酸素活性化機構の解明"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T06:25:23.496133+00:00"}
