Appel, Rolf; Montenarh, Mathias published the artcile< Preparation of silylated amidosulfuric acid derivatives and their reaction with sulfur(IV) halides>, Synthetic Route of 25999-04-6, the main research area is aminosulfamide silylation; sulfamide silylation; sulfur halide sulfamide; diimide sulfur disulfamoyl; sulfinylamine thiobis.
The silylation of aminosulfamides, R2NSO2NH2 with HN(SiMe3)2 gave R2NSO2NHSiMe3 (R = Me, Et; R2N = piperidino, morpholino). Me2NSO2NHSiMe3 was lithiated and silylated with Me3SiCl to give Me3NSO2N(SiMe3)2 (I), also prepared from Me2NSO2NH2 and Me3SiCl. ROSO2NH2 [R = H (II), Me) was silylated with Me3SiCl to give ROSO2NR1SiMe3 (R = Me3Si, R1 = H; R = Me, R1 = Me3Si). II and Me3SiCl also gave Me3SiOSO2N(SiMe3)2 (III), also prepared from (Me3Si)3N and SO3. I and II with SOCl2 gave RSO2NSO [R = Me2N (IV), Me3SiO]. S(NSO)2 was prepared from [(Me3Si)2N]2SO2 and SOCl2, from Me3SiNSO and SO2Cl2, and from Me3SiN:S:NSiMe3 and SOCl2. IV was heated to give Me2NSO2N:S:NSO2NMe2, also prepared from I and SF4. I and SF4 also gave Me2NSO2N:SF2 (V), also prepared from IV and SF4. V and N(SiMe3)3 gave Me2NSO2N:S:NSiMe3.
