We demonstrate a novel crosslinked disulfide system as a cathode material for Li-S cells that is designed with the two criteria of having only a single point of S?S scission and maximizing the ratio of S?S to the electrochemically inactive framework. The
Tris(thioacetals) from benzene hexathiol: Towards covalent self-assembly

Mixtures of isomers are available from the reaction of benzene hexathiol with three equivalents of p-tolualdehyde and kinetic traps avoided under the reported catalytic conditions, establishing tris(thioacetals) as potential building blocks for covalently self-assembled complex structures.

Density functional theory energies, geometries, and population analyses as well as nucleus-independent chemical shifts (NICS) have been used to investigate the structural and magnetic evidence for cyclic CnS n2- and CnSn (n = 3-6) electron delocalization. Localized molecular orbital contributions to NICS, computed by the individual gauge for localized orbitals method, dissect π effects from the σ single bonds and lone pair influences. CnS n2- (n = 3-5) structures in Dnh symmetry are minima. Their aromaticity decreases with increasing ring size. C 3S32- is both σ and π aromatic, while C4S42- and C5S5 2- are much less aromatic. NICS(0)π, the C-C(π) contribution to NICS(0) (i.e., at the ring center), decreases gradually with ring size. In contrast, cyclic C6S62- prefers D2h symmetry due to the balance between aromaticity, strain energy, and the S-S bond energies and is as aromatic as benzene. The theoretical prediction that C6S66- has D6h minima was confirmed by X-ray structure analysis. Comparisons between thiocarbons and oxocarbons based on dissected NICS analysis show that CnSn 2- (n = 3-5) and C6S66- are less aromatic in Dnh symmetry than their oxocarbon analogues.
Benzenehexathiol as a Template Rim for a Golden Wheel: Synthesis and Structure of 6>

The reaction of benzenehexathiol, C6(SH)6, with in the presence of triethylamine gave the hexanuclear gold(I) compound 6> whose structure has been determined; the hexagon of the central benzene carbon atoms is surrounded by a hexagon of sulfur atoms, followed by a hexagon of gold atoms and the wheel-like structure is completed by six peripheral phosphine ligands with interlocked aryl groups.
