It has been found that treatment of SF5-alkyl halides, especially SF5(CH2)(2)Br, with silver salts such as CH3C(O)OAg, p-CH3C6H4SO3Ag, CF3SO3Ag and AgNO3 provides convenient pathways for preparing the following ester compounds: SF5CH2CH2R (R = CH3COO, TosO, CF3SO3, NO3) SF5(CH2)(3)OTos, and SF5(CF2)...
