Abstract

NEW MATERIAL:An N-substituted-Δ1-tetrahydrophthalimide derivative expressed by formulaI(R1 is halogen; R2 is H or halogen; R3 is H or lower alkyl; R4 is alkyl having a cyano group).
EXAMPLE: N-[4-Chloro-3-( 1'-cyanoethoxy )carbonylphenyl]-Δ1-tetrahydrophthalimide.
USE: A herbicide, capable of exhibiting a high weeding activity, and improved weeding effects on annula and perenyial weeds in paddy fields even in a small amount of the chemical, and further effects by the pre-emergence treatment and treatment in the growth period in plowed fields.
PROCESS: A compound expressed by formula II is reacted with a compound expressed by formula III under mild conditions to give a compound expressed by formula IV, which is then cyclized under heating or esterified to afford a compound expressed by formula V. The resultant compound expressed by formula V is then cyclized under heating to give the compound expressed by formulaI.
