| titleOfInvention | Process for the preparation of diesters of alpha, omega dicarboxylic acids |
| abstract | Process for the preparation of alpha, omega-dicarboxylic acid diesters of the general formula I <IMAGE> in which R¹, R², R³, R <4>, R <5>: hydrogen, C1- to C20-alkyl, C2- to C20-alkenyl, C2 to C20 alkynyl, C2 to C20 alkoxycarbonyl, nitro, C1 to C20 alkoxy and / or cyano and; n: an integer from 1 to 12, characterized in that cycloalkanones of the general formula II <IMAGE> in which R¹, R², R³, R <4>, R <5> and n have the abovementioned meanings, with dimethyl carbonate in the presence of a nitrogen-containing base of the general formula III <IMAGE> in which R <6>, R <7>, R <8>: hydrogen, C1- to C20-alkyl, C3- to C8-cycloalkyl or C7- to C20- Aralkyl or R <6> and R <7> together mean a C2 to C7 alkylene chain which is optionally monosubstituted to fivefold by R¹, reacted at temperatures from 50 to 300.degree. |
