The title compound (MeSO2)2N-SO2-O-SiMe3 (2; m.p. 57 deg C) is obtained by treating (MeSO2)2N-SiMe3 (3) with one equivalent of sulfur trioxide in CH2Cl2 at -20 deg C.The crystal structure of 2 (triclinic, space group P) was established by low-temperature X-ray diffraction.The most interesting feature of the molecular structure is the geometry of the S-O-Si sequence, displaying a very long Si(sp3)-O bond, a short S(sp3)-O bond and a large angle at oxygen (mean values for two independent molecules: Si-O 174.1, S-O 151.1 pm, S-O-Si 134.3 deg).The coordination at nitrogen is trigonal-planar (S-N-S 118.5-121.0 deg, S-N 170.5-173.1 pm). 2 is instantaneously hydrolyzed by excess water to form (MeSO2)2NH, sulfuric acid and (Me3Si)2O.In vacuo at 60 deg C, molten 2 will readily dissociate into its precursors 3 and SO3.It is shown that 2 may react either as an SO3 donor or as a sulfosilylating reagent.Reaction with Lewis bases such as Me3N, pyridine or R2PCl (R = tBu, Ph) proceeds with the formation of the corresponding complexes B*SO3; thermolysis of the isolable phosphane complexes affords the respective phosphane oxides R2(Cl)PO.Sulfosilylation of phenol, cyclohexene or 2,3-dimethyl-2-butene with 2 in CH2Cl2 gives the trimethylsilyl esters of 4-hydroxybenzenesulfonic, cyclohexene-3-sulfonic, or 2,3-dimethyl-1-butene-3-sulfonic acids, respectively.Key words: Trimethylsilyl N,N-dimesylamidosulfonate, synthesis, X-ray structure, long Si(sp3)-O bond, SO3 transfer, sulfosilylation.
