Three new routes to derivatives of alpha-fluoracrylic acid, including a laboratory synthesis and a large-scale method, are reported. The processes are (i) addition of elementary fluorine to acrylic esters and subsequent elimination of HF; (ii) addition of difluorocarbene to isopropenyl methyl ether, oxidation via ring opening and dehalogenation; and (iii) 'nitrofluorination' of 2,3-dichloropropene, hydrolysis and dechlorination.
