Polysulfonylamines, XXXVI, Trimethylsilyl Dimesylamine: Preparation, NMR-Spectroscopic Characterization, and Reactivity as a Silylating Agent

(CH3)3SiN(SO2CH3)2 (1), m.p. 69-70 deg C, is obtained by metathesis of AgN(SO2CH3)2 with (CH3)3SiCl (improvement of a known procedure) or, more conveniently, by silylation of HN(SO2CH3)2 with 2NH.The (1)H, (13)C and (29)Si NMR solution spectra and the (29)Si NMR solid-state spectrum suggest the constitution of 1 in solution (CDCl3, CD2Cl2, CDCl2-CDCl2) to be an equilibrium mixture of the N-silylated form (CH3)3Si-N(SO2CH3)2 (I) and the O-silylated form (CH3)3Si-O-S(O)(CH3) = NSO2CH3 (II) in a molar ratio of 2:1 at room temperature, whereas in the known crystal structure of 1 only form I is present.The solid-state NMR experiment acted as a bridge between X-ray crystallography and solution-state NMR, enabling assignments of the resonances to be made with confidence to the tautomers.At room temperature, form II undergoes a rapid intramolecular 1.5-migration of silicon between oxygen centers of the two sulfonyl groups.As shown by kinetic measurements using (1)H NMR spectroscopy, 1 is a highly reactive agent for silylating ketones in the presence of triethylamine.Hydroxy and thiol functions, even when sterically hindered, are silylated by 1 in uncatalyzed reactions.It is further shown that HN(SO2CH3)2 is an efficient catalyst for silylations with 2NH.
