Divergent Synthesis of Trifluoromethyl Sulfoxides and β-SCF<sub>3</sub> Carbonyl Compounds by Tandem Trifluoromethylthiolation/Rearrangement of Allylic and Propargylic Alcohols
A selenium-catalyzed trifluoromethylthiolation/[2,3]-sigmatropic rearrangement of tertiary allylic and propargylic alcohols which could provide straightforward and facile access to trifluoromethyl sulfoxides was developed. Various allylic and allenic trifluoromethyl sulfoxides were obtained with moderate to excellent yields. Meanwhile, a Lewis acid mediated trifluoromethylthiolation/1,2-rearrangement

A selenium-catalyzed trifluoromethylsulfinylation/rearrangement of allylic and propargylic alcohols for synthesizing triflones was developed for the first time. Various allylic and allenic triflones were delivered in moderate to excellent yields. After numerous control experiments were performed, it was suggested that this transformation includes an unusual [+SCF3] group disproportionation process
