Abstract: The carbonyl derivatives at m-position of phenyl of phenyl-1,2,3,6-tetrahydro phthal imide (I) for herbicide is prepared by (1) reacting alpha-carbonyl compounds and N-(2-fluoro-4-chloro- 5-hydroxyphenyl) -1,2,3,6-tetrahydro phthalimide (IV) from 1,2,3,6-tetrahydro phthalate and 2-fluoro- 4-chloro- 5-hydroxy aniline to get N-fluoro-4-chloro- 5-O-[1-(2,4-dichlorophenyl0 ethane-1-on-2-yl - 1,2,3,6-tetrahydro phthalimide (VI) which has carbonyl group, (2) reacting (VI) and hydroxyl amines to get (I). (I) as herbicide is useful for tomato, wheat, soybean, corn and rice.
