| abstract |
The invention relates to a method for producing a N-alkylated aniline of formula (I) Ar-N(R<1>)2-n(CHR<2>CHR<3>Ar')n by reacting an aromatic olefin of formula (II) Ar'CR<3>=CHR<2> with an aniline of formula (III) Ar-N(R<1>)2-n(H)n in an inert solvent and in the presence of at least one basic catalyst selected from the group of alkali alcoholates and alkaline-earth alcoholates or alkali amides and alkaline-earth amides, whereby in formulas (I) to (III); Ar and Ar', independent of one another, represent an aryl radical selected from the group of the condensed and non-condensed C6-C22-aromatic compounds and of the condensed or non-condensed C5-C22-heteroatoms which contain at least one nitrogen, oxygen or sulfur atom in the ring; R1, R2, R3, independent of one another, represent a hydrogen atom, a C1-C8-alkyl radical or an aryl radical Ar; and n represents the number 1 or 2. |
