Abstract
N-.alpha.-alkoxyethyl carboxylic compounds of the formula ##STR1## wherein R.sup.5 means hydrogen, an alkyl group having from 1 to 6 carbon atoms or an aryl group having from 6 to 10 carbon atoms, especially hydrogen or a methyl group, and Wherein R.sup.6 means an alkyl group having from 1 to 6 carbon atoms, especially a methyl group, Are prepared by electrolysis of secondary N-ethylcarboxylic acid amides of the formula ##STR2## with alcohols of the formula R.sup.6 OH, R.sup.5 and R.sup.6 having the aforesaid meaning, while employing tetraalkyl ammonium tetrafluoroborates, tetraalkyl ammonium hexafluorophosphates as well as alkali-tetrafluoroborates as conducting salts and a current quantity of at least 2.5 Faraday/mole of N-ethylcarboxylic acid amide. The N-.alpha.-alkylethyl compounds are valuable intermediate products for the preparation of N-vinyl carboxylic acid amides which may then be converted to water-soluble polymers having multiple properties for technical application.
