Abstract
NEW MATERIAL:A pyrazole derivative expressed by formula I (R1 is H or lower alkyl; R2 is lower alkyl or lower alkenyl; X is halogen, nitro, lower alkyl or lower alkoxyl; n is 0 or an integer 1W3; X may be the same or different when n is 2 or 3; Y is alipathic or aromatic imido or heterocyclic ring group).
USE: A herbicide capable of causing the chlorosis and killing weeds.
PROCESS: A compound expressed by formula II is reacted with a compound expressed by formula III (Hal is halogen), preferably in a solvent, e.g. an aromatic hydrocarbon and a ketone, and in the presence of a deacidifying agent.
