Compounds corresponding to the formula: ##SPC1## In which R.sub.1 and R.sub.2 are, independently, hydrogen, alkyl, alkoxyalkyl, cycloalkyl, pinonyl, ethylcycloalkyl, lower alkenyl, halogenated lower alkyl, benzyl, ethylphenyl, 2,4-dichlorophenoxy-methylene, styryl, furyl, phenyl or substituted phenyl in which the substituents are nitro, halogen, methyl, or methoxy; R.sub.3 and R.sub.4 are, independently, hydrogen or lower alkyl; X and Y are independently oxygen or sulfur; and Z is halogen, nitro, amino, lower alkyl, lower alkoxy or trifluoromethyl and n is an integer having a value from 0 to 4. The above compounds are effective herbicides, particularly for the control of grasses and broadleaf plants with both pre-emergence and post-emergence activity. Representative compounds are: m-propionamidobutyranilide, m-bis-2,2-dimethylvaleranilide, m-isobutyramido trichloroacetanilide, m-isobutyramido-2-ethylbutyranilide, m-t-butylacetamidopropanilide, and 3'-N-ethyl propionamido-propanilide.
根据公式:##SPC1## 其中R₁和R₂分别独立为氢、烷基、烷氧基烷基、环烷基、松油基、乙基环烷基、低碳烯基、卤代低碳烷基、苄基、乙基苯基、2,4-二氯苯氧基亚甲基、苯乙烯基、呋喃基、苯基或取代的苯基,其中取代基为硝基、卤素、甲基或甲氧基;R₃和R₄分别独立为氢或低碳烷基;X和Y分别独立为氧或硫;Z为卤素、硝基、氨基、低碳烷基、低碳烷氧基或三氟甲基,n为0至4的整数。上述化合物是有效的除草剂,特别适用于控制具有出土前后活性的禾本科植物和阔叶植物。代表性的化合物有:m-丙酸酰胺丁酰苯胺、m-双-2,2-二甲基戊酰胺、m-异丁酰胺三氯乙酰苯胺、m-异丁酰胺-2-乙基丁酰苯胺、m-叔丁基乙酰胺丙酰苯胺和3'-N-乙基丙酰胺丙酰苯胺。
