WebSynthèse. Le chimiste allemand Peter Lipp vers 1930 a l’idée de synthétiser la cyclopropanone à partir de cétène et de diazométhane.La réaction dans l'éther diéthylique conduit toutefois à la cyclobutanone. Il suppose donc que cela provient de la cétone sur un cycle à trois (la cyclopropanone), apparemment très réactive, qui agit comme produit … Web中文别名: 3-(Boc-氨基)-1-环丁酮(MSDS,154748-49-9) 英文别名: 3-(Boc-amino)cyclobutanone;3-(Boc-amino)cyclobutanone: CAS号: 154748-49-9: SMILES
