Abstract
Abstract F-4-Methyl-2-pentene 1 in highly polar solvents undergoes the fluoride ion promoted isomerisation to F-2-methyl-2- pentene 2 , which by addition of fluoride ion forms F-2- methyl-2-pentylcarbanion 3 . Carbanion 3 was alkylated with alkyl halided 4 to give hydrofluorocarbons 5 in high yields. In the reaction of carbanion 3 with 1-iodo-3,3,3-trifluoropropane 6 no alkylation products but equimolar amounts of 3,3,3-trifluoropropene 7 and 2-H-F-2-methylpentane 8 were formed. Reaction of carbanion 3 with 1,3-diiodopropane 9 resulted in formation of alkene 10 and alkane 8 , while with diiododes 11 , where n≥4, the expected disubstituted hydrofluoroalkanes 12 were obtained.
