The invention relates to a method for producing alkoxy malonic acid dinitriles of general formula (I), wherein R
1
means C
1
-
6
-alkyl or halogen-substituted C
1-6
-alkyl. The method is characterised in that the corresponding alkoxy malonic acid diamides of general formula (II), wherein R
1
has the aforementioned meaning, are converted by means of a dehydrating agent. The invention also relates to the intermediate products of general formula (III), whereby said products are formed during dehydration.
A process for preparing 2-cyno-2-alkoxyacetamides of the formula:
1
where R
1
is C
1-16
-alkyl or halogen-substituted C
1-16
-alkyl, wherein appropriate alkoxymalonamides of the general formula:
2
where R
1
is as defined above, are reacted with a dehydrating agent and the reaction is stopped before the reaction continues to 2-cyano-2-alkoxyacetamides (I).
