Abstract
NEW MATERIAL:The N'-[4-(2-alkenylthio)phenyl]-N,N-dimethylurea derivative of formula I (R1, R2 and R3 are H or lower alkyl; X is H, Cl or Br; excluding the compound wherein R1 is methyl, R2 and R3 are H, and X is H, Cl or Br and the compound wherein R1 and R3 are H, R2 is methyl, and X is H, Cl or Br).
EXAMPLE: N'-[3-Chloro-4-(2-propenylthio)phenyl]-N,N-dimethylurea.
USE: A selective herbicide having high inter-genus selectivity between rice plant and barnyard grass, and strong herbicidal activity against a wide variety of weeds by the photosynthesis-inhibiting activity. It has low toxicity.
PROCESS: The compound of formula I is prepared by reacting the 4-(2-alkenylthio) phenyl isocyanate derivative of formula II with dimethylamine in the absence of presence of solvent such as organic solvent, under cooling, at room temperature or under heating.
