A new class of crown ethers containing a hydrazine moiety was synthesized in only 2, 3, or 4 steps starting from 1,2-diacetylhydrazine or 1,2-diethylhydrazine. Hydrazino-crown ethers with 2 or 4 nitrogen atoms in the ring were obtained by reacting the hydrazine derivatives with 1,11-diiodo-(or dichloro)-3,6,9-trioxaundecane, 4-allyloxymethyl-1,8-diiodo-3,6-dioxaoctane, 3-chloro-2-chloromethyl-1-propene
从1,2-二乙酰肼或1,2-二乙基肼开始,仅用2、3或4个步骤就合成了一种新的含有肼部分的冠醚。通过使肼衍生物与1,11-二碘-(或二氯)-3,6,9-三氧杂十一烷,4-烯丙氧基甲基-1,8-二碘- 3,6-二氧杂辛烷,3-氯-2-氯甲基-1-丙烯,1,10-二苄基-1,10-二氮杂-3,7-二氧杂十二烷或二甘氨酰二氯化物(随后还原)。二氮杂肼基19-冠-6化合物与甲基氯化铵形成络合物。
