N-Mono- and NN-disubstituted fluoracetamides have been tested as potential larvicides, contact insecticides and rodenticides. All monosubstituted amides were toxic to larvae of Musca vicina Macq. at a concentration of 100 p.p.m. Disubstituted amides were inactive or only slightly active. Only the amides monosubstituted by relatively small aryl radicals (phenyl, p-tolyl, p-fluorophenyl and p-chlorophenyl)
N-单取代和 NN-二取代氟乙酰胺已被测试为潜在的杀幼虫剂、接触杀虫剂和杀鼠剂。所有单取代酰胺对 Musca vicina Macq 的幼虫都有毒性。在 100 ppm 的浓度下,双取代酰胺没有活性或只有轻微活性。只有被相对较小的芳基(苯基、对甲苯基、对氟苯基和对氯苯基)单取代的酰胺对成年麝香鼠表现出接触毒性。一种对 DDT 具有高度抗性的菌株。所有化合物对实验室大鼠都是有毒的。具有小芳基的 N-单芳基酰胺的近似 LD50 值最低(4 至 8 毫克/千克)。具有较大芳基取代基(α-和β-萘基、对二苯基和对溴苯基)的那些具有稍高的 LD50 值。N-芳基酰胺的摩尔 LD50 值落在一个狭窄的范围内。
