Both 1,1,1,3,3,3-hexamethyldisilazane and N,O-bis-(trimethylsilyl)acetamide have been shown to suppress the formation of abnormal aromatic Claisen rearrangement products by efficiently trapping the incipient normal products as their silyl ethers under mild conditions.
1,1,1,1,3,3,3-六甲基二硅氮烷和N,O-双-(三甲基甲硅烷基)乙酰胺均已显示可通过有效捕获初始的正常产物(如甲硅烷基醚)来抑制异常的芳族克莱森重排产物的形成。温和的条件。
