Fluorinated Β-hydroxy-Β-carbomethoxy acids and photoreduction of their copper salts

Conclusions The methyl esters of fluorinated -keto acids enter into the Knoevenagel condensation with malonic acid and give fluorinated -hydroxy--carbomethoxy acids, which form copper salts with a ligand:copper composition=1:1. The Cu salts of fluorinated -hydroxy--carbomethoxy acids are photoreduced by alcohols in the presence of UV light to give -hydroxy--carbomethoxy acids and metallic Cu.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 8, pp. 1896–1900, August, 1982.
