Heteroaromatic substituted diimidosulfinates

Polyimido Sulfur(VI) Phosphanyl Ligand in Metal Complexation

“…[12a] A superposition plot of the core of both complexes is depicted in Figure 3. A comparison of the bond angles and lengths of both complexes revealed that the SÀN distances in 1 are shorter in comparison to the S IV analogue (165.20 (9) and : S1ÀN1 1.5804(10), S1ÀN2 1.5705(11), S1ÀN3 1.5389(11), Li1ÀN1 2.006(3), Li1ÀN2 1.977(2), SÀC1 1.8181(12), PÀC1 1.8513(12), N1-S1-N2 97.49(5), S1-C1-P1 111.76(6), C1-S-N3 95.90(6), N1-Li1-N2 72.99(8), N4-Li1-N5 82.94 (16). 171.84(10) pm) because of the higher oxidation state of the sulfur atom.…”

“…[15] Sulfur/nitrogen compounds of this type have already been employed in the synthesis for various metal complexes with versatile coordination motifs, [11] but the combination with transition metals has rarely been touched to date. [16] One advantage of the sulfur triimides over the sulfur diimides is their additional coordination site that can be employed in the syntheses of heterobimetallic complexes. [3d] To explore the field of sulfur imides in combination with transition metals, the new Janus head scorpionate [(tmeda)Li-{(NtBu) 3 SCH 2 PPh 2 }] (1) and the transition metals manganese, nickel, and zinc were used in the syntheses.…”

Magnesium Diimidosulfinates – Conformational Studies in the Solid State and in Solution

“…Indeed, monomers could only be crystallized in the presence of a polydentate donor base such as TMEDA. [15] [(thf)MgCl{(NtBu) 2 SPh}] 2 (1) is no exception to this rule of thumb as it crystallizes as a dimer with a central four-membered Mg 2 Cl 2 ring (Figure 1). Except for the central Mg 2 X 2 ring, 1 exhibits essentially the same bond lengths and angles, within their standard deviation, as its heavier congener [(thf)MgBr{(NSiMe 3 ) 2 -SPh}] 2 (6).…”

π-Spacer-coupled Diimidosulfinates

“…In contrast to the diimidosulfinates described in the literature, the molecule does not dimerize but accomplishes the favored fourfold coordination of the lithium atom by coordination of two THF molecules. Up to now monomeric diimidosulfinates have only been known with a chelating donor base like TMEDA [31]. Otherwise only triimidosulfinates or the S(N t Bu) 4 2− anion have been known to crystallize as monomers when THF is the only donor base present [32,33].…”
