The alkoxide-catalyzed addition of alcohols 2 to α-chloroacrylonitrile (1) at -35°C gives rise to 3-alkoxy-2-chloropropanenitriles 3; at 0–5°C with excess 2 alkyl 3-alkoxy-2-chloropropanimidates 4 are obtained. The yields of 3 or 4 decrease with increasing pKa values of the alcohols 2. In the base-catalyzed addition of phenols 5 to 1, a temperature-dependent addition equilibrium is set up in which
