Diaminosulfur Diimide, the Aza Analog of Sulfuric Acid

Raman Spectroscopic Investigation and Coordination Behavior of the Polyimido SVI Anions [RS(NR)3]− and [S(NR)4]2−

“…[26] 4 ] 2À ). [28] Unfortunately it is only characterized by elemental analysis and no structural information is available. Lithium(tert-butyl)amide easily adds to N,N'-di(tert-butyl)sulfur diimide to give [Li 4 {(NtBu) 3 S} 2 ].…”

Syntheses and Characterization of Polyimidosulfate Complexes

“…[22,31] The first sulfur atom with fourfold coordination and consequently the first known analog of the sulfate anion SO4 2-was synthesized by Appel and Ross in 1968. [32] The S,S-dimethylsulfurdiimide reacted with potassium amide in liquid ammonia to give the tripotassium salt of sulfodiimine [K3(HN)3SN • NH3] (Scheme 1.4). [32] Scheme 1.4: Synthesis of [K3(HN)4SN • NH3].…”
