In order to obtain sulfonylurea herbicides with good crop safety for both wheat and corn, while maintaining high herbicidal activities, a series of pyrimidine- and triazine-based diethylamino-substituted chlorsulfuron derivatives I [R1 = Me, MeO, p-tolyl, etc.; R2 = CH,N; R3 = H, Me, MeO, Cl] were systematically evaluated. The structures of the synthesized compounds I were confirmed with 1H NMR, 13C NMR and HRMS. The preliminary biol. assay results indicate that the 4,6-disubstituted pyrimidine and triazine derivatives could maintain high herbicidal activity. It was found that the synthesized compounds I could accelerate degradation rates, both in acidic and alk. soil. Especially, in alk. soil, the degradation rate of the target compounds I accelerated more than 22-fold compared to chlorsulfuron. Moreover, most chlorsulfuron analogs I exhibited good crop safety for both wheat and corn at high dosages. This study provided a reference for the further design of new sulfonylurea herbicides I with high herbicidal activity, fast degradation rates and high crop safety. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0HPLC of Formula: 102-09-0).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 102-09-0
