文摘In order to search for new types of herbicides,a series of ethyl 4 hetercyclic(aryl)amino sulfonyl phenoxy acetates(propionates) were synthesized by the condensation reactions of 4 ethoxycarbonylmethylenoxy(ethoxy)phenyl sulfonyl chlorides and saturated heterocyclic(aryl)amines.Their structures were confirmed by 1H NMR,IR,MS and elemental analysis.The results of biloassays showed that some of the new compounds have good herbicidal activities.
