of the disclosure: Compounds of the formula in which R4 represents an alkyl radical having from 1 to 4 carbon atoms, R5 represents a linear or branched alkylene radical having from 1 to 10 carbon atoms in the chain which may be substituted by groups which are not reactive under the applied conditions, and R6 represents hydrogen or a branched alkyl radical having from 3 to 10 carbon atoms with a secondary or tertiary N-.alpha.-C atom, are prepared by anodic alkoxylation of lactams of the formula with an alcohol of the formula R4OH, in which formulae R4, R5 and R6 have the aforesaid meaning, in the presence of at least one alkali metal or tetraalkylammonium tetrafluoroborate, hexafluoroborate or nitrate as conducting salt at a temperature of up to about 100.degree. C in an electrolytic cell with stationary or flowing electrolyte. Some of the products are novel. They can be used as intermediates for the manufacture of pharmaceuticals, antistatic agents in textile industries and as intermediates for polymerization reactions and for the preparation of ?-amino-?,.omega.-dicarboxylic acids. |
