Versuchsvorschrift
According to the previously described general procedure (GP1), Knoevenagel condensation (75° C.; 6 h) between 4-(trifluoromethoxy)benzaldehyde (10.000 g; 52.598 mmol) and malonic acid (10.399 g; 99.937 mmol) gave the product 3-(4-trifluoromethoxy-phenyl)-acrylic acid as a colorless solid (12.080 g; 99%). LC-MS: tR=0.96 min.; [M+H]+: no ionisation.
