Two series of 2-cyano-3-substituted-pyridinemethylaminoacrylates, namely 12 new (Z)-2- cyano-3-methylthio-3-substituted-pyridinemethaneaminoacrylates and 10 new (Z)-2-cyano- 3-alkyl-3-substituted-pyridinemethaneaminoacrylates, were synthesized as herbicidal inhibitors of photosystem II (PSII) electron transport. All of these compounds were confirmed by 1H NMR, elemental, IR, and mass spectrum analyses. Their herbicidal activities were ...
