A mixture of the bisadducts was obtained by the reaction of C60 with an -formylsulfonium ylide, and then separated into fifteen fractions by preparative HPLC, preparative TLC, and recycling preparative HPLC. Fourteen of fifteen fractions were found to consist of a single isomer, respectively, which were assigned to the trans-2 (3 diastereo-isomers), trans-3 (3 diastereo-isomers), trans-4 (3 diastereo-isomers), equarorial (2 diastereo-isomers), and cis-2 (3 diastereo-isomers) bisadducts by the comparison of their UV/vis spectra with those of the bisadducts obtained by the Bingel-Hirsch reaction. The 1H- and 13C-NMR analysis, the transformation of the formyl groups, and the dipole moment calculation clarified the stereochemistry of the subsitutents on the two cyclopropane bridge-head carbons (in/in, in/out, and out/out).","subitem_description_type":"Abstract"}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_2_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1016/j.tetlet.2005.10.027","subitem_relation_type_select":"DOI"}}]},"item_2_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.elsevier.com/locate/issn/00404039","subitem_relation_type_select":"URI"}}]},"item_2_select_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00404039","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Saigo, Kazuhiko"}],"nameIdentifiers":[{"nameIdentifier":"105793","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ito, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"105794","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishida, Yasuhiro"}],"nameIdentifiers":[{"nameIdentifier":"105795","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-26"}],"displaytype":"detail","filename":"17_Elsevier_w.pdf","filesize":[{"value":"113.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"17_Elsevier_w.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/54/files/17_Elsevier_w.pdf"},"version_id":"6c8dfc9f-2b97-4d33-8c43-4e029aac9cd2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Bifunctionalization","subitem_subject_scheme":"Other"},{"subitem_subject":"Diastereo-isomer","subitem_subject_scheme":"Other"},{"subitem_subject":"α-Formylsulfonium ylide","subitem_subject_scheme":"Other"},{"subitem_subject":"Fullerene","subitem_subject_scheme":"Other"},{"subitem_subject":"Regio-isomer","subitem_subject_scheme":"Other"}]},"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":"Preparation and identification of bis(formylmethano)[60]fullerene isomers: The first systematic study on bifunctionalized [60]fullerenes with dissymmetric addends","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Preparation and identification of bis(formylmethano)[60]fullerene isomers: The first systematic study on bifunctionalized [60]fullerenes with dissymmetric addends"}]},"item_type_id":"2","owner":"1","path":["11","19"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-05-10"},"publish_date":"2007-05-10","publish_status":"0","recid":"54","relation_version_is_last":true,"title":["Preparation and identification of bis(formylmethano)[60]fullerene isomers: The first systematic study on bifunctionalized [60]fullerenes with dissymmetric addends"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:40:57.836087+00:00"}
