[Aims] The purpose is to design and synthesize novel acrylonitrile derivatives and to evaluate its herbicidal activities. [Methods] α-Carbonyl acetonitrile were synthesized using substituted acetonitriles as the raw materials by acylation reactions. Then fourteen novel title compounds were synthesized by condensation reaction of substituted amines with α-carbonyl acetonitrile intermediates. [Results] The structure of the compounds were confirmed by ~1HNMR and MS. The preliminary bioassay showed that the target compounds exhibited good herbicidal activities at the concentration of 200 mg/L. For example, compounds ZJ1, ZJ7 and ZJ8 displayed over 90% inhibition against stems and roots of sorghum and rape. [Conclusions] The herbicidal activities of the target compounds were better than that of pyribambenz isopropyl.
