Oligoethylenepiperazines and their derivatives of the formula ##SPC1## Wherein n is a positive integer of 1 to 7 inclusive; m is zero or one when n=1, or m is one when n=2.about.7 R.sub.1 is hydrogen, benzenesulfonyl or benzenesulfonyl ring substituted by at least one member selected from the group consisting of lower alkyl of 1-4 carbon atoms, nitro and amino; R.sub.2 is halogen when m=zero and hydrogen, benzenesulfonyl or benzenesulfonyl ring substituted by at least one member selected from the group consisting of lower alkyl of 1-4 carbon atoms, nitro and amino when m=one; and the cationic salts thereof are useful as anion exchange oligomers, antihelmintic compounds, and intermediates for the preparation of polymers and fine industrial chemicals.
寡乙烯基哌嗪及其衍生物的化学式为:##SPC1##
其中,n为1至7的正整数;当n=1时,m为0或1;当n=2至7时,m为1。R1为氢、苯磺酰基或苯磺酰基环上至少有一种成员选自1-4碳原子的低级烷基、硝基和氨基的取代基。当m=0时,R2为卤素;当m=1时,R2为氢、苯磺酰基或苯磺酰基环上至少有一种成员选自1-4碳原子的低级烷基、硝基和氨基的取代基。它们的阳离子盐可用作阴离子交换寡聚体、抗寄生虫化合物以及聚合物和精细工业化学品的中间体。
