Lead tetraacetate (LTA) can smoothly induce the addition reaction of difluorodiiodomethane (1) with electron-rich alkenes at 60°C in diglyme to give monoadducts (RCHICH2CF2I) and diadducts (RCHICH2)2. The similar, clean reaction of fluoroolefins, such as tetrafluoroethene, hexafluoropropene, with 1 occurs only in acetic acid. However, non-fluorinated β-iodo-α,β-unsaturated carboxylic esters are obtained when 1 reacts with alkynes in alcohol. The iododifluoromethyl radical generated by possible pathways from 1 with LTA is discussed.

Various 3-alkyl-5-polyfluoroalkyl-2-isoxazoline derivatives have been synthesized in moderate yield by the 1,3-dipolar cycloaddition reaction of nitroalkanes via their trimethylsilyl esters with polyfluoroalkylethenes.

Per(poly)fluoroalkyl aldehydes can be conveniently synthesized from per(poly)fluoralkyl chlorides by their reaction with DMF promoted by a PbBr2(catalyst)/Al bimetal redox system at room temperature.
