Yield:5232-99-5 94.1%
Reaction Conditions:
with ammonium acetate;pyrographite in n-heptane for 15 h;Ionic liquid;Reflux;
Steps:
4-7 Example 6 Preparation of ethyl 2-cyano-3,3-diphenylacrylate
According to the scheme in Example 4,Where ammonium acetate feeding scheme,Add 10g for the first time, after 1h of reaction,Then add 1.5g every half hour, the total reaction time is about 15h,The rest is unchanged, and finally the ethyl 2-cyano-3,3-diphenylacrylate is 117.1g,The yield was 94.1%, and the HPLC purity was 99.3%.
