中文摘要：

N-氰基-S，S-二甲基二硫代碳酸酯在THF中与亚膦酸二烷基酯的钠盐反应得到中间体；再与多种芳甲胺反应合成了九个未见文献报导的N-氰基-N＇-取代芳甲基脒基膦酸酯类化合物（3a-3i），其结构经。HNMR，^31P NMR，HR-MS或元素分析表征。初步生物活性测试结果表明，当用药浓度为10ppm时，3对黄瓜子叶生根具有一定的促进作用，对蚜虫和红蜘蛛没有抑制活性。

英文摘要：

Nine novel N-cyano-N＇-arylmethyl carbarnimidoyl phosphonates（3a - 3i） were synthesized through the reaction of various arylmethyl amines with N-cyanoimido-phosphonyl/S-methyl thiocarbonates at room temperature. The structures were characterized by ^1H NMR, ^31p NMR, HR-MS or elemental analysis. Preliminary bioassay indicated that some of 3 stimulated certain radicle growth of cucumber at 10 ppm.
