Synthesis and herbicidal activity of substituted penenoxyacetamide pyrimidine derivatives

Eight new N'-(4,6-disubstituedpyrimidin-2-yl)-N-substitutedphenoxyacet-amides were synthesized and characterized. The structures of these compounds were determined by HNMR,IR and elemental analysis.The preliminary herbicidal tests show that some of the title compounds have inhibitory activity against weeds.
