This reaction involves the intramolecular 1,2-silicon shift from carbon to carbon. The spectroscopic properties of these silyl ketones have been measured.\nThe ketones obtained here react with various halogen acids under milder conditions compared to that of their carbon analogs to give the ring opening products, 3-chloropropyl silyl ketones, or the ring enlargement products, 2-silyl-4,5-dihydrofuran derivatives in some cases. The reaction with sulfuric acid or trifluoromethane sulfonic acid affords only the corrensponding silyldihydrofurans in good yield. Especially, it is noteworty that the reaction of 2-phenylcyclopropyl silyl ketone with sulfuric acid yields 2-phenylcyclobutanone. The formation of these comounds is interpreted on the basis of the effect that silicon stabilizes a cation to it.\nWittig reactions of cyclopropyl silyl ketones with alkylidene-triphenylphosphoranes proceed stereoselectively to give the corresponding Z-1-silyl-1-cyclopropyl alkenes. The protiodesilylation of silyl cyclopropyl alkenes with tetrabutylammonium fluoride proceeds with retention of configuration to give E-cyclopropyl alkenes, although the reaction with hydrogen halides was unsuccessful due to the cleavage of the three membered ring.\nThe reaction of sulfur ylides in THF with cyclopropyl silyl ketones resulted in the formation of the corresponding siloxyalkenes or -ketosilanes. The relative ratio of these compounds varies with the reaction temperature, the porality of solvents used, and the preparation method of ylide. It is noteworthy that the reaction with salt free ylide affords siloxyalkenes and that of the ylide containing inorganic salt -ketosilanes, selectively. These two type of products would be formed by the anionotropic and cationotropic rearrangement of silyl group in the betaine intermediate.","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:62550627, 研究期間(年度):1987 – 1988","subitem_description_type":"Other"},{"subitem_description":"出典:研究課題「シクロプロピルトリメチルシリルケトン類の新合成法とその有機合成への応用」課題番号62550627\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-62550627/625506271988kenkyu_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":"金沢大学工学部","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00067725","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=70019735"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=70019735","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-62550627/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-62550627/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-62550627/625506271988kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-62550627/625506271988kenkyu_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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-10-31"}],"displaytype":"detail","filename":"TE-PR-NAKAJIMA-T-kaken 1990-2p.pdf","filesize":[{"value":"90.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"E-PR-NAKAJIMA-T-kaken 1990-2p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/61482/files/TE-PR-NAKAJIMA-T-kaken 1990-2p.pdf"},"version_id":"49fa3fce-8ef3-4af0-9c21-ded0aff25db2"}]},"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":"シクロプロピルトリメチルシリルケトン類の新合成法とその有機合成への応用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"シクロプロピルトリメチルシリルケトン類の新合成法とその有機合成への応用"},{"subitem_title":"Novel preparation method and synthetic applications of cyclopropyl trimethylsilyl ketones","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2845"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-10-31"},"publish_date":"2022-10-31","publish_status":"0","recid":"61482","relation_version_is_last":true,"title":["シクロプロピルトリメチルシリルケトン類の新合成法とその有機合成への応用"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T11:53:09.956273+00:00"}
