    Abstract: A process for preparing 4-dialkoxymethylpyrazoles of the formula I ##STR1## where R.sup.1 is n-alkyl,R.sup.2 is a hydrocarbon radical,R.sup.3 and R.sup.4 are each hydrogen, a hydrocarbon radical, cyano, halogen or alkoxycarbonyl,entails electrochemical oxidation of a 4-methylpyrazole of the formula II ##STR2## in the presence of an alkanol R.sup.1 --OH.
