Considering that trifluoromethyl benzyl alcohol can be prepared via the addition of benzaldehyde and Ruppert-Prakash reagent, we next investigated the one-pot reaction of benzaldehyde, TMSCF3 and sulfonyl fluoride. Pleasingly, under the mediation of CsF, the desired sulfonate 3a was farmed in 85% yield (Scheme 1, eq. 1). The analogous multicomponent of TMSCF2H, benzaldehyde and sulfonyl fluoride 2a was also tested and the desired product 5a was obtained 80% yield (Scheme 1, eq. 2).
