Abstract

Novel 1 - (substituted phenyl) - 3,6 - endo-methylene - D 4 - tetrahydrophthalimide derivarives of general formula <FORM:1056908/C2/1> wherein R represents an ortho-positioned C1-atom or a para-positioned-OC2H5 group, are prepared by (a) reaction of 3,6-endomethylene-D 4 -tetrahydrophthalic anhydride with the required substituted aniline, and (b) reaction of N-(substituted phenyl)-maleimide with cyclopentadiene in accordance with the Diels-Alder reaction. N - (o - chlorophenyl) - maleimide is prepared by the reaction of o-chloro-aniline and 3,6-endomethylene - D 4 - tetrahydrophthalic anhydride. N-(p-ethoxyphenyl)-maleimide is prepared by a similar method.
