In most cases, fluorination by molecular fluorine has been carried out using fluorotrichloromethane (expensive) as the solvent and hence, the method as a whole is considered uneconomical. However, as stated below, solvent was not indispensable for this kind of fluorination reaction.

Since 6a belongs to the class of so-called hypervalent molecules (molecules with more than an octet of electrons around the central atom), one should consider the participation of electron-rich three-center bonding. The results suggests that the best stabilization will arise when the terminal atoms of the trigonal bipyramidal structure are electron-negative ones. Martin J. C., Science, 221, 509 (1983); Albright T. A., Burdett J. K., Whangbo, M-H., "Orbital Interactions in Chemistry," John Wiley & Sons, New York, 1985, pp. 258-276.

2O/ AcONa was reported to give the α-acetoxylated sulfides in good yields. High temperature as well as the presence of base (AcONa) might be necessary for the required deprotonation. See, Masuda T., Numata T., Furukawa N., Oae S., J. Chem. Soc., Perkin Trans. 2, 1979, 1302.
