The condensation of α,α-dichloropropionyl chloride (IVa) and of trichloroacetyl chloride (IVb) with α-chloropropionyl chloride (Ia) in the presence of triethylamine led to two acid chloride enol-esters, both as mixtures of cis- and trans-isomers, namely 1, 2-dichloropropenyl α,α-dichloropropionate (Va) and 1, 2-dichloropropenyl trichloroacetate (Vb).
