Some chloroacetamide derivatives were synthesized from 2,6-dialkyl, aniline 4-chloroaniline, or 3,4-dichloroaniline with alkyl 2-bromopropionate and chloroacetyl chloride and identified by elemental analyses, NMR, and GC/MS spectra as N-(1'-methoxycarbonylethyl)-N-chloroacetyl-2,6-dimethylaniline(AC...

Some chloroacetamide derivatives were synthesized from 2,6-dialkyl, aniline 4-chloroaniline, or 3,4-dichloroaniline with alkyl 2-bromopropionate and chloroacetyl chloride and identified by elemental analyses, NMR, and GC/MS spectra as N-(1'-methoxycarbonylethyl)-N-chloroacetyl-2,6-dimethylaniline(ACRI-S-8609), etc. These compounds synthesized were subjected to the test for pre-emergence herbicidal effecs on some grass weeds(Digitaria adscendens, Setaria viridis, Echinochloa crus-galli) and broad leaf weeds(Portulaca oleracea, Amaranthus lividus, Chenopodium album) in pots applied as wettable powder formulations. It was found that N-(1'-ethoxycarbonylethyl)-N-chloroacetyl-2,6-dimethylaniline(ACRI-S-8701) has the highest herbicidal effect on grass weeds, which corresponds to a 95% control effect at an application of 200g a.i/10a. Whereas, some chloroacetamide derivatives derived from 4-chloroaniline or 3,4-dichloroaniline had very weak herbicidal effects on grass and broad leaf weeds.
