Purification Methods

Wash the solid with a little CCl4, then H2O to remove traces of pyridine sulfate, and dry it over P2O5. [Baumgarten Chem Ber 59 1166 1926, Olah et al. Synthesis 59 1979, Beilstein 20/5 V 184].

Check Digit Verification of cas no

The CAS Registry Mumber 26412-87-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,4,1 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26412-87:
(7*2)+(6*6)+(5*4)+(4*1)+(3*2)+(2*8)+(1*7)=103
103 % 10 = 3
So 26412-87-3 is a valid CAS Registry Number.

POLYSULFONYLAMINE: TEIL LXXI. EIN MOLEKUEL MIT EINER LANGEN Si(sp3)-O-BINDUNG: SYNTHESE, STRUKTUR UND REAKTIVITAET VON N,N-DIMESYLAMIDOSCHWEFELSAEURETRIMETHYLSILYLESTER

Hiemisch, Oliver,Blaschette, Armand,Jones, Peter G.

, p. 161 - 172 (2007/10/03)

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.
