Procedure
The process according to the invention is carried out in three stages: dimethyl α-fluoromalonate is first reacted with formaldehyde to give dimethyl α-hydroxymethyl-α-fluoromalonate, the latter is then hydrolyzed and the hydrolysis product is decarboxylated and dehydrated, and finally, the resuiting α-fluoroacrylic acid is esterified with a substituted phenol.
