Perfluoroalkylcalcium derivatives, prepared by the action of perfluoroalkyl iodides on amalgamated calcium in ethers, react with aldehydes and ketones to give the expected alcohols in 20–70% yields.

Perfluoroalkyl iodides, RFI, react in ethers with aldehydes and ketones in the presence of calcium to give the alcohols RFC(OH)R1R2. The best yields (20–70%) were obtained with Ca/Hg amalgam in THF as solvent at −20 to −40°C. The new alcohols were characterized by 1H and 19F NMR and mass spectrometry. The results are interpreted in terms of the intermediate formation of an organocalcium species.
全氟烷基碘化物R F I在醚中与醛和酮在钙存在下反应,得到醇R F C(OH)R1R2。在-20至-40°C的温度下,使用THF中的Ca / Hg汞齐作为溶剂可获得最佳收率(20–70%)。通过1 H和19 F NMR和质谱对新型醇进行表征。根据有机钙物质的中间形成来解释结果。
