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