An iron-catalyzed thiocyclization of propynols with aryl disulfides has been developed for the synthesis of trifluoromethylated benzothiophenes. The one-pot tandem reaction involves Meyer-Schuster -rearrangement of propynols and radical cyclization through C-H functionalization of aryl disulfides. A variety of 2-trifluoroacyl benzothiophenes were prepared in moderate to good yields with good functional-group tolerance.

Hydroiodonation of trifluoromethyl propargylic alcohols 1 regio- and stereoselectively produce (Z)-2-iodo-3-trifluoromethyl allylic alcohols 2. (Z)-2-Alkynyl-3-trifluoromethyl allylic alcohols 5, available through Pd(PPh3)4-mediated coupling of 2 and terminal alkynes 4, cyclize and subsequently isomerize to 3-trifluoroethylfurans 6 upon catalysis under PdCl2(CH3CN)2 in THF at 5-10°C.
