Crystal Structure and Herbicidal Activity of 5,7-Dimethoxy-(2,4-dichlorophenoxyacetyl-imino)-2H-1,2,4-thiadiazolo2,3-apyrimidine

摘要

The title compound 5,7-dimethoxy-(2,4-dichlorophenoxyacetylimino)-2H-1,2,4- thiadiazolo[2,3-a]pyrimidine has been synthesized. In order to investigate the relationship between the structure and herbicidal activity of the target compound, we report its crystal structure and herbi- cidal behavior in the present paper.
