title: Efficient synthesis of trifluoromethylated cyclopentadienes/fulvenes/norbornenes from divinyl ketones.
abstract: The synthetic methods of trifluoromethylated cyclopentadienes/fulvenes/norbornenes have been developed using 3-CF3-1,4-dien-3-ols as the synthons, which can be easily prepared by the regiospecific 1,2-addition of the Ruppert–Prakash reagent (TMSCF3) to divinyl ketones. All the reactions are carried out under mild, metal-free conditions to afford the corresponding products in high to excellent yields.
