摘要:
[5-(1,3-dimethylureido)-1,3,4-thiadiazol-2-ylthio]-acetic acid methylester (b.p. 113.degree. C.), [5-(1,3,3-trimethylureido)-1,3,4-thiadiazol-2-ylthio]-acetic acid ethylester (b.p. 95.degree. C.) and [5-(3-methylureido)-1,3,4-thiadiazol-2-ylthio]-acetic acid isopropylester (b.p. 143.degree. C.) in which R is hydrogen or alkyl. The compounds are useful as the active agents or one of the active agents in herbicidal compositions.
