The titanium tetrachloride-mediated addition of allyltrimethylsilane or 1,8-bis(trimethylsilyl)-2,6-octadiene and trifluoroacetic anhydride led to trifluoromethyldiallylcarbinol or (dl)-1-trifluoromethyl-2,5- divinylcyclopentanol, respectively, in fair yields; this latter was further converted into several 1-trifluoromethyl-2-vinylcyclopentane derivatives.
