y-ray induced addition of acetaldehyde to perfluoro-3,4-dimethyl-3-hexene gives a product which, in two novel steps, may be converted to a fluorinated furan. In pursuing the unusual chemistry of fluorinated olefins of the type (RF)2C=C(RF)2 ' (where RF is a perfluoroalkyl group) we find that free-r

2,5-Dimethylfuran (1) and 2-pivaloyloxymethylfuran (4) were alkylated with 1-iodo-perfluorohexane using sodium dithionite as radical initiator. Perfluorohexylation in the 2-position accompanied with dimerization was observed forming the products 2, 3 and 5, respectively.
