Compounds corresponding to the formula: ##STR1## 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-butylacetamido-propionanilide, and 3'-N-ethyl propionamido-propionailide.
具有以下公式的化合物:##STR1##
其中R.sub.1和R.sub.2分别是氢、烷基、烷氧基烷基、环烷基、脱水松香烷基、乙基环烷基、较低烯基、卤代较低烷基、苄基、乙基苯基、2,4-二氯苯氧基-亚甲基、亚苯基、呋喃基、苯基或取代苯基,其中取代基是硝基、卤素、甲基或甲氧基;R.sub.3和R.sub.4分别是氢或较低烷基;X和Y分别是氧或硫;Z是卤素、硝基、氨基、较低烷基、较低烷氧基或三氟甲基,n是一个整数,其值从0到4。上述化合物是有效的除草剂,特别用于控制草本植物和双子叶植物,既具有前期活性又具有后期活性。代表性化合物包括:m-丙酰胺丁酰苯胺、m-双-2,2-二甲基戊酰苯胺、m-异丁酰三氯乙酰苯胺、m-异丁酰-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。
