Through progress in understanding the reactivity of SF 5 halides (SF 5 X), both primary synthons, SF 5 Br and SF 5 Cl were utilized in order to synthesize the benzotrifluoride analog, pentafluorothiobenzene (SF 5 C 6 H 5 ) from cyclohexene or derivatives of cyclohexene. These new processes readily produce pentafluorothiobenzene in high yields. One may consider SF 5 C 6 H 5 a primary synthon in its own right and it has found application ...
