Abstract
The invention comprises substituted succinimides of the formula <FORM:0725945/IV (b)/1> wherein R is hydrogen or a methyl radical, and their preparation by reacting a -(o-chlorophenyl)-a -methyl succinic acid or its anhydride with ammonia or methylamine, and heating the intermediate product so obtained (which may be a half-amide, its ammonium or methylamine salt or the mono- or di-salt of the acid, depending upon the quantities of reagents taken) to a temperature between 100 DEG and 350 DEG C. a - (o - Chlorophenyl) - a - methyl succinic acid is prepared from ethyl a -cyano-b -(o-chlorophenyl)-b -methyl acrylate by treatment with ethanolic potassium cyanide followed by acid hydrolysis. The corresponding a - (o - chlorophenyl) - a - methyl succinic anhydride is obtained from the acid using acetyl chloride.
