An Alternative Synthesis of Sodium Cyanodithioformate and the Disodium Salt of cis-1,2-Dicyanoethylene-1,2-dithiol

A new synthesis of sodium cyanodithioformate 1 and the disodium salt of cis-1,2-dicyanoethylene-1,2-dithiol 2 is reported. The key step involves a nucleophilic thiolation with elemental sulfur starting from a substituted acetonitrile 4. This method may serve as a cyanide- and carbondisulfide-free alternative in the preparation of the title compounds.

Monolayers and Langmuir-Blodgett Films of a Newly Synthesized Asymmetric Tetraazaporphyrin Derivative

Molecular assemblies such as monolayers at the water-air interface and Langmuir-Blodgett films of 2,3-bis(N-(3-thiopropyl)phthalimido)-7,8,12,13,17,18-hexakis(octylthio)-5,10,15,20-tetraazaporphyrinato (TAP) copper(II) and nickel(II) derivatives were studied for the first time.Monolayers at the water-air interface both of the pure macrocyclic derivative and of its mixture with stearic acid were investigated.The degree of order within Langmuir-Blodgett films was established with the aid of UV-vis and ESR spectroscopies.The surface behavior of the above unsymmetrically substituted TAP, in the form of metal derivatives, has been compared with that of the corresponding symmetrically substituted compounds (Bonosi; et al.J.Phys.Chem. 1993, 97, 9181), which give disordered films.We report here on the improved ordering in the LB film fabrication reached with the unsymmetrical substitution as being due to the presence of the hydrophilic phthalimide moieties in two of the eight long chains around the TAP skeleton, which favor an edge-on orientation of the macrocycle at the air-water interface.

Thiacyanocarbons. 5. Reactions of Tetracyano-1,4-dithiin and Tetracyanothiophene with Nucleophiles: Synthesis of Tetracyanopyrrole and Tetracyanocyclopentadiene Salts

Reactions at the double bonds of tetracyano-1,4-dithiin and tetracyanothiophene have been explored.Generally, nucleophiles attack the dithiin by an addition-elimination mechanism to produce divinyl sulfides.The resulting anions are stable, experience fragmentation, or undergo further condensation reactions to produce heterocyclic structures.For example, tetracyano-1,4-dithiin is converted by thiocyanate ion to a thiophenopyrimidine.In fragmentation reactions, the dithiin acts as a masked maleonitrile and as such is useful for the synthesis of tetracyanoethylene.Remarkably, the dithiin reacts with sodium azide to give tetracyanopyrrole and with reactive methyl compounds to give substituted tetracyanocyclopentadienide ions.Tetracyanothiophene reacts with nucleophiles in a manner similar to tetracyanodithiin but at higher temperatures.
