Synthesis of 2‑Aryl-3-fluoro-5-silylthiophenes via a Cascade Reactive Sequence

2-Aryl-3-fluoro-5-silylthiophenes were readily prepared only in two steps from 2-bromo-3,3,3-trifluoropropene in good yields. These transformations include the first successful S_N2′-type reaction of 2-bromo-3,3,3-trifluoropropene and benzylthiols and [2,3]sigmatropic rearrangement of 2-bromo-3,3-difluoroallyl benzyl sulfide
