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。
