Sulfur diimides bearing dialkylboryl and bis(amino)boryl substituents-studied by multinuclear magnetic resonance spectroscopy

Article abstract of DOI:10.1080/10426509808545467

Reactions of metallated sulfur diimides, K(NSN)R (R = ^tBu, SiMe₃, P^tBu₂) and K(NSN)K, with various boron chlorides R¹₂,BCl (R¹ = _tBu, ^cpent, Et₂N, ⁱPr₂N), [CH₂N(R¹)]₂BCl (R^l = Me, ⁿBu, ^lPr, ^tBu) and R¹R²NBCl₂ (R¹ = R² = Et, iPr ; R¹ = PhCH₂, R² = ^tBu; R¹ = PhCH₂, R² = Ph) lead to the corresponding boryl-substituted sulfur diimides 2 - 8, 9a -20a, 9b, 11b - 13b, 17b and 15c.The sulfur diimides (Et₂N)₂B(NSN)SiMe₃ (11b) and (ⁱPr₂N)₂B(NSN)^tBu (12a) react with hexachlorodisilane by cleavage of the Si-Si bond to give the new bis(amino)sulfanes 21b and 22a, in which the nitrogen atoms bear additional SiCl₃ substituents. A complete NMR spectroscopic study was carried out for the known cyclic sulfur diimide ⁱPr₂B(NSN)₂BNⁱPr₂ (1). All non-cyclic compounds were studied by ¹H, ¹¹B, ¹³C and ¹⁵N NMR at variable temperature aiming for configurational assignment. The ¹⁵N NMR data, in particular, suggest that in most cases almost linear N=S-B units are preferred with a perpendicular arrangement of the plane of the boryl group with respect to the NSN plane.
