Abstract
2,6-Difluorobenzoylthiourea was synthesized by the reaction of 2-amino-4,6-dimethoxyl pyrimidine with 2,6-difluorobenzoyl isosulfocyanic ester from 2,6-difluorocarboxylic acid by chloration and acylate,its structure was characterized by IR and(()~1HNMR) spectra and elemental analysis.The primary factors of effect on reaction were discussed.The preliminary biologic tests showed that these compounds had good herbicidal activity.
