β-CF3-α,β-diphenylvinyl sulfide 3a was prepared stereoselectively in 77% yield from the reaction of 2 with phenyllithium at room temperature for 5 h. Oxidation of 3a with MCPBA afforded the corresponding vinyl sulfone 4a, in which (E)-4a can be

The stereoselective preparation and Pd-catalyzed cross-coupling reaction of boronates 2 provides a new general and convenient route to CF 3-substituted triaryl ethenes 3, in which the CF3 and Ar3 groups are cis to each other. The synthetic potential was demonstrated by the total synthesis of panomifene (Ar1 = Ar 3 = Ph, Ar2 = 4-(OHCH2CH2NHCH 2CH2O)-C6H4). Bpin = (pinacolato)boryl.
