Conclusions

  1. 1.

    The electrophillic cleavage of alkyl fluorides from the esters ofα-trifluoromethyl-β,β-dialkoxy-acrylic acids leads to the formation of esters of difluoromethylenemalonic acid.

  2. 2.

    During the reaction between the dimethyl ester of difluoromethylenemalonic acid and trimethylphosphite, a stable adduct is formed, which when heated splits into methyl difluorophosphite and the dimethyl ester of dimethoxymethylenemalonic acid.
