Abstract

Abstract New compounds corresponding to the formula: IN WHICH R1 is hydrogen, lower alkyl, or lower alkenyl; R2 is alkyl, lower alkenyl, cycloalkyl, phenyl or substituted phenyl in which the substituents are lower alkyl, lower alkoxy, nitro or halogen; and R3 is hydrogen, lower alkyl, cycloalkyl having 3 to 4 carbon atoms, inclusive, halogenated lower alkyl, lower alkenyl, furyl or benzyl; provided that when R1 is hydrogen or lower alkyl R3 is other than lower alkyl and further provided that when R1 is hydrogen and R2 is methyl, R3 is other than hydrogen, halogenated lower alkyl, cycloalkyl or lower alkenyl. The above-defined compounds are effective herbicides, particularly for the control of grasses and broadleaf plants with both pre-emergence and post-emergence activity. Representative compounds are: 3''-(N-n,propylcarbamoyloxy)cyclopropane carboxanilide, 3''-(N-n-butylcarbamoyloxy)crotonanilide, 3''-(Nethylcarbamoyloxy)furoyl anilide, 3''-(N,N-diallylcarbamoyloxy) propionanilide, 3''-(N-n-propylcarbamoyloxy)vinylacetanilide and 3''-(N-i-propylcarbamoyloxy)2-bromo isobutyranilide.
