As shown in Scheme 1, the propargyl alcohols S3,S4 were prepared by the nucleophilic reaction of lithium acetylide, which was generated via a Corey-Fuchs reaction from benzaldehyde S1 and the corresponding benzophenones. The resulting propargyl alcohols S3,S4 were treated with CF3SO3H (TfOH) to give the desired triarylpropargyl cation salts 1 + TfO -,2 + TfO -as red solids. Although the addition of water causes degradation of the molecules, the salts of propargyl cations are thermally stable and can be handled in an ambient atmosphere.
