Hydrogen halide formed is continuously removed from the organic solvent, halogenated Rirenkarubon acid imide by a halogen element in a two-phase mixture comprising an organic solvent and water

摘要

General formula I [wherein, have the following meanings variables: A, of B, when n or imide group is 1 taken together, B and A is 1 or is Hal both It is hydrogen, independently of one another R, R ¹ is; which is a hydrogen group and the other and a and Hal group number: hetaryl alkyl, cycloalkyl, aryl or optionally substituted; are Hal, chlorine, bromine aralkyl or iodine; are n, is 1, 2 or 3; wherein, x is, 'B' and group A of the general formula II Rirenkarubon acid imides are halogenated] 2 to 8, and when n or an imide group together is 1, both produced by reacting in the presence of an organic solvent L1 inert and halogen element and Rirenkarubon acid imide] is hydrogen A method for, is characterized in that continuously withdrawing the hydrogen halide formed during the reaction from the solvent L1, preparation of Rirenkarubon acid imides are halogenated of the general formula I.
