Abstract

NEW MATERIAL:A N-(p-benzyloxyphenyl)-3,4,5,6-tetrahydrophthalisoimide of formula I: (R1 and R2 are H or CH3 groups; R3 is H, halogen, or lower alkyl group).
USE: Herbicides effective for barnyard grass and three-square grass which are narrow leaved weeds, very little damage to rice plants, and useful before and after the rice-planting.
PROCESS: A 2-[(p-benzyloxyphenyl) carbamoyl]-1-cyclohexene-1-carboxylic acid of formula II is dehydrated in the presence of dicyclohexylcarbodiimide of formula III or trifluoroacetic anhydride and triethylamine in a solvent, e.g. CCl4, THF, or dioxane, at-10W50°C to give the desired compound of formula I.
