Tertiary perfluoroalkyl bromides (R(F)Br) in nonpolar solvents under mild conditions can be added to the multiple bond of terminal alkenes, alkynes, and butadiene. Slow addition to alkenes at 20-degrees-C is accelerated in proton-donating solvents and is catalyzed by readily oxidizable nucleophiles. Bromination of the multiple bond and formation of R(F)Br reduction products suggests a radical-chain mechanism initiated by electron transfer to the R(F)Br molecule.
