Unsaturated α-diazocarbonyl compounds undergo intramolecular cyclopropanation or carbon-hydrogen bond insertion when catalyzed by Rh2(OAc)4: α-diazo ketones react preferentially with carbon-carbon doubled bond, whereas closely related α-diazo-β-keto-esters insert into carbon-hydrogen bond.
当不饱和的α-重氮羰基化合物被Rh 2(OAc)4催化时,会发生分子内环丙烷化或碳氢键插入:α-重氮酮优先与碳-碳双键反应,而紧密相关的α-重氮-β-酮酯插入物变成碳氢键。
