O,S-Dialkyl ((piperazinyl)carbonyl)phosphoramidothioates are prepared by the reaction of O,S-dialkyl phosphoroisocyanatidothioates with substituted piperazines and found to be effective plant systemic and contact insecticides. ((4-(1,1-Dimethylethyl)-1-piperazinyl)carbonyl)phosphoramidothioate, for example, is prepared from O,S-dimethyl phosphoroisocyanatidothioate and 4-(1,1-dimethylethyl)piperazine and found to control aster leafhoppers when applied to rice plants.
O,S-二烷基(哌嗪基)羰基磷酰氨基硫酸酯是通过O,S-二烷基磷酰异腈基硫酸酯与取代哌嗪的反应制备的,发现其具有有效的植物系统性和接触杀虫剂作用。例如,(4-(1,1-二甲基乙基)-1-哌嗪基)羰基磷酰氨基硫酸酯是由O,S-二甲基磷酰异腈基硫酸酯和4-(1,1-二甲基乙基)哌嗪制备的,并发现当施用于水稻植株时,可以控制飞蝨叶跳虫。
