Abstract

A process for preparing &bgr;-alkoxynitriles by reacting &agr;,&bgr;-unsaturated nitriles with monohydric, dihydric or trihydric alcohols in the presence of basic catalysts at from −20 to +200° C. comprises using a diazabicycloalkene catalyst of the formula I where from 1 to 4 hydrogen atoms may be independently replaced by the radicals R1 to R4, in which caseR1, R2, R3, R4 are each C1-20-alkyl, C6-20-aryl or C7-20-arylalkyl, andn and m are each an integer from 1 to 6.
