Preparation, structures, and physical properties of tetrakis(alkylthio) tetraselenafulvalene (TTCn-TSeF, n = 1-15)

A series of tetrakis(alkylthio)tetraselenafulvalene compounds (TTC n-TSeF, n = 1-15) were prepared by a one-step reaction between dialkyl disulfide and tetralithiated TSeF. Molecular properties (redox potentials and optical absorptions in solution) and solid-state properties (thermal behaviors, electric conductivities, and molecular and crystal structures for n = 1 and 10) were studied. TTCn-TSeF compounds are weak electron donor molecules and characterized by small on-site Coulomb repulsion. TTC1-TSeF has a high-dimensional conduction network owing to the presence of highdimensional heteroatomic contacts, "Atomic-Wire Effect." The π-moieties of TTC10-TSeF were fastened by the alkyl chains ("Fastener Effect") to form π-columns and there are a variety of short heteroatomic contacts resulting in two dimensional electronic structure. Electrical conductivity exhibited peculiar enhancement for n = 1 and 7 ≤ n ≤ 14 owing to the presence of high-dimensional conduction paths. These compounds may manifest high carrier mobility, and are good candidates for the field-effect transistor channel based on the advantageous features: low dark conductivity, low donor ability, on-site Coulomb repulsion energy, high-dimensional π-electron structure, and high solubility in organic solvents.

Cobalt phthalocyanine mediated aerobic oxidation of thiols: A simple and convenient preparation of disulphides

Cobalt phthalocyaninetetrasulphonamide/tetrasodium salt of cobalt tetrasulphophthalocyanine catalyzed oxidation with molecular oxygen form a simple, efficient and environmentally acceptable synthetic tool for the oxidation of thiols to disulphides in excellent yields, under mild conditions and without any side reactions.

Heterogeneous permanganate oxidation of thiols

The products that may be obtained from the oxidation of thiols by permanganate under heterogeneous conditions have been compared with those that are known to be produced by use of the same oxidant under homogeneous conditions. The products obtained from the oxidation of thiols under homogeneous and heterogeneous conditions are distinctively different. Sulfonic acids are obtained under homogeneous conditions, while disulfides are the only detectable products when the reactions are carried out heterogeneously. For example, a quantitative yield of dibutyl disulfide is obtained from the oxidation of butane-1-thiol, and oxidation of pentane-1,5- dithiol gives the corresponding cyclic disulfide, 1,2-dithiepane.
