The reaction of bis(trimethylsilyl) sulfate (BTS) with HBr leads to trimethylbromosilane, hexamethyldisiloxane, and free bromine. Its reaction products with HI are hexamethyldisiloxane and free iodine. The reaction of BTS with PCl3 leads to the formation of Me3SiCl, SO2, and a polymeric product whose composition approximates [(CH3)3SiO]8Cl2O27P8S4. The reaction of SOCl2 with BTS gives in high yield Me3SiOSO2Cl, Me3SiCl, and SO2. POCl3 and SO2Cl2 do not react with BTS under analogous conditions.
