α-Fluoro-β-haloacrylic acids are formed when the esters ofα-fluoro-α,β-dihalopropionic acids are heated with aqueous alkali, followed by acidification.
The heat dehydrochlorination of the acid chloride ofα-fluoro-α,β-dichloropropionic acid gives the acid chloride ofα-fluoro-β-chloroacrylic acid.
Methyl (α-fluoro-β-chlorovinyl) ketone was synthesized.
