P-H spirophosphorane (16) was synthesized utilizing the new bidentate ligand, and the structure of 16 was essentially the same as that of the P-H phosphorane with the Martin ligands (1b). Phosphoranes which exhibit reversed apicophilicity (9: O-equatorial) were also synthesized and could be converted to the corresponding stable stereoisomers (10: O-apical). The crystal structures of O-equatorial phosphoranes (9) and those of O-apical isomers (10) were slightly affected by the steric repulsion of pentafluoroethyl groups. Kinetic measurements revealed that the stereomutation of O-equatorial methylphosphorane (9a) to the O-apical isomer (10a) was slowed. The activation enthalpy for the stereomutation of 9a→10a (24.4 kcal mol–1) was higher than that of the phosphorane bearing the Martin ligands (3a→4a: 19.3 kcal mol–1) by 5.1 kcal mol–1.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Wiley-VCH Verlag GmbH"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"1861-4728","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA12151701","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"314"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2007","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicPageEnd":"323","bibliographicPageStart":"314","bibliographicVolumeNumber":"2","bibliographic_titles":[{"bibliographic_title":"Chemistry - An Asian Journal"},{"bibliographic_title":"Chemistry - An Asian Journal"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_b1a7d7d4d402bcce","subitem_version_type":"AO"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/asia.200600334","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1002/asia.200600334","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"ChemAsianJ_2-2_314.pdf","filesize":[{"value":"1.2 MB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2006634/files/ChemAsianJ_2-2_314.pdf"},"version_id":"021f8f46-c2ce-4f50-929a-1dc74349ddb0"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"20645"},"item_title":"Synthesis and application of a bidentate ligand based on decafluoro-3-phenyl-3-pentanol : Steric effect of pentafluoroethyl groups on the stereomutation of O-equatorial C-apical spirophosphoranes","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2006634","relation_version_is_last":true,"title":["Synthesis and application of a bidentate ligand based on decafluoro-3-phenyl-3-pentanol : Steric effect of pentafluoroethyl groups on the stereomutation of O-equatorial C-apical spirophosphoranes"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T08:04:19.645460+00:00"}
