Synthesis of (<i>E</i>)- and (<i>Z</i>)-2,3-Bis(trifluoromethyl)allyl Alcohols by γ-Ray Irradiation of Hexafluoro-2-butyne with Alcohols and Some Reactions
Radiation-induced addition reaction of alcohols to hexafluoro-2-butyne provided (E)- and (Z)-2,3-bis(trifluoromethyl)allyl alcohols, which were dehydrated to afford 1,2-bis(trifluoromethyl)-1,3-butadienes. Thermal cyclization of 3-methyl-1,2-bis(trifluoromethyl)-1,3-butadiene afforded 1-methyl-2,3-bis(trifluoromethyl)clobutene.
