The reaction of Huisgen zwitterion, derived from triphenylphosphine and dialkyl azodicarboxylate, with diaryl-1,2-diones afforded N,N-dicarboalkoxy monohydrazones via a mechanistically novel rearrangement. Cyclic and acyclic ketones furnished vinyl hydrazinedicarboxylates under similar conditions.
衍生自三苯基膦和偶氮二羧酸二烷基酯的 Huisgen 两性离子与二芳基 1,2-二酮的反应通过机械上新颖的重排得到 N,N-二碳烷氧基单腙。环状和非环状酮在相似条件下提供乙烯基肼二羧酸盐。
