Abstract:

Diamagnetic niobium and tantalum complexes of general formula [M(η5-C5Me5)(dithiolene)2] have been prepared (M = Nb, dithiolene = dddt2 (5,6-dihydro-1,4dithiine-2,3-dithiolate) (1); M = Ta, dithiolene = dddt2 (2); M = Nb, dithiolene = dddt2 and dmit2 (1,3-dithiole-2-thione-4,5-dithiolate) (3)). All these complexes exhibit temperature-dependent 1H NMR spectra which result from a fluxional behavior of the dithiolene ligands. Their redox properties have been investigated by cyclic voltammetry and reversible oxidation processes involving the dithiolene ligands have been evidenced for the compl

Abstract:

According to MNDO calculations on 1,2-dithiete (IIIa), 1,2-dithiin (IVa) and 3,4-dimethylene-1,2-dithiane (Va) the closed-ring compounds are thermodynamically more stable than the open-chain compounds whereas the reverse holds for 4-methylene-1,2-dithiole (VIa). Substitution of the exocyclic CH2 group of VIa by O, S, NH, and OH+ stabilizes its cyclic mesoionic structure. The low triplet state energy of VIa and of some derivatives relative to the lowest singlet state energy signalizes the biradicaloid nature of these electronic structures.

We present a series of compounds by exploiting the unusual 1,4-aryl shift observed for electron-rich 1,3-dithiole-2-thione and tetrathiafulvalene (TTF) derivatives in the presence of perchloric acid.

In the crystal, the benzoic acid molecules are linkedviaO—H...O hydrogen bonds, forming inversion dimers withR22(8) motifs. The dimers are linked through weak C—H...O hydrogen bonds into a chain structur

Abstract:

3H-1,2-Dithiole-3-thiones are among the best studied classes of polysulfur-containing heterocycles due to the almost explosive recent interest in these compounds as sources of hydrogen sulfide as an endogenously produced gaseous signaling molecule. This review covers the recent developments in the synthesis of these heterocycles, including both well-known procedures and important novel transformations for building the 1,2-dithiole-3-thione ring. Diverse ring transformations of 3H-1,2-dithiole-3-thiones into various heterocyclic systems through 1,3-dipolar cycloaddition, replacement of one or t

Conditions for ENDOR measurem ents of organosulfur radical cations are discussed and tested. The one electron oxidation of a variety of aromatic sulfur com pounds comprising benzene-1,2-dithiole, 1,4-dithiine, thianthrene and diphenylsulfide derivatives as well as 33S isotope-marked bis(2,5-dimethoxyphenyl)disulfide is accomplished using the oxygen-free, powerful and selective AlCl3/H2CCl2 reagent. Partly with substantial structural changes, paramagnetic M⊕ species of 1,2-benzodithiete, 1,4-dithiine, thianthrene and diphenyl sulfide result. Their temperature-dependent ENDOR signal patterns pro

Abstract:

Tetrakis(o-xylylenedithio)phthalocyanine 5 and its nickel complex 5-Ni were treated with aluminum chloride in toluene to eliminate the peripheral o-xylylene groups. The thiolate anions generated from 5 and 5-Ni were reacted with carbonyldiimidazole to produce phthalocyanines 6 and 6-Ni with four 1,3-dithiole-2-one rings, respectively. Phthalocyanine 7a having four ethylenedithiotetrathiafulvalene units was prepared via the condensation of 6-Ni with ethylenedithio-1,3-dithiole-2-thiones. The reaction of 6-Ni with bis(methylthio)-1,3-dithiole-2-thiones gave phthalocyanine 7b with the correspondi

Abstract:

Reactions of nitrile, amide or ester of 5-amino-3-thioxo-3H-1,2-dithiole-4-carboxylic acid 1 with alkylation and acylation agents were studied. "Ionic" 1,2-dithiole amides 6 were formed in several ways. Treatment with phosphorus pentasulfide afforded the corresponding 3,3aλ4,4-trithia-1-azapentalenes 7. Structures of the synthesized heterocycles were studied using a combination of X-ray analysis, IR spectroscopy, and HF and DFT quantum-chemical calculations.
