The radical addition reactions of 2-benzoyloxypentafluoropropene [CF2=C(CF3
)OCOC6H5] (BPFP), an F-enol ester, with cyclopentane, cyclohexane and cyclo
heptane in the presence of benzoyl peroxide are shown to afford the 1:1 add
ition products of BPFP with the cycloalkanes. The structures of the reactio
n products were confirmed by the mass spectra and H-1, C-13 and F-19 NMR me
asurements. Similar additions of perfluoroisopropenyl cyclohexanecarboxylat
e with cycloalkanes were also investigated. (C) 1999 Elsevier Science S.A.
