1, 1-Disubstituted hydrazines were prepared from the corresponding 1, 1-disubstituted ureas by means of the Hofmann rearrangement reaction. The yields were fairly good, except from the ureas susceptible to oxidation, and thus the present method represents an additional and efficient procedure for the synthesis of 1, 1-disubstituted hydrazines.
通过Hofmann重排反应,从相应的1,1-二取代
脲制备了1,1-二取代
肼。除易被氧化
脲外,产率相当好,因此本方法为1,1-二取代
肼的合成提供了一种额外且高效的途径。
