[H5PV2Mo10O40] catalyzed oxidation of dithiols to related cyclic disulfides. Potassium permanganate as an oxidizing reagent under mild conditions was carried out in this reaction. This system provides an efficient, convenient, and practical method for the syntheses of cyclic disulfides. In this work, the comparisons among the Keggin and Dawson ions are addressed in term of relative stability hardness and acidity. Copyright Taylor & Francis Group, LLC.

The effect of the nature of the dithiolato ligand on the physical and electrochemical properties of synthetic H-cluster mimics of the [FeFe]-hydrogenase is still of significant concern. In this report we describe the cyclization of various alkanedithiols to afford cyclic disulfide, tetrasulfide, and hexasulfide compounds. The latter compounds were used as proligands for the synthesis of a series of [FeFe]-hydrogenase H-cluster mimics having the general formulas [Fe2(CO)6{μ-S(CH2)nS}] (n = 4-8), [Fe2(CO)6{μ-S(CH2)nS}]2 (n = 6-8), and [Fe2(CO)6{(μ-S(CH2)nS)2}] (n = 6-8). The resulting complexes were characterized by 1H and 13C{1H} NMR and IR spectroscopic techniques, mass spectrometry, and elemental analysis as well as X-ray analysis. The purpose of this research was to study the influence of the systematic increase of n from 2 to 7 on the redox potentials of the models and the catalytic ability in the presence of acetic acid (AcOH) by applying cyclic voltammetry.

experimental part, p. 521 - 531 (2012/04/23)
Several poly(alkylene sulfide)s have been synthesized in excellent yields from reactions of α,ω-dibromo- and/or α,ω- dichloroalkanes with sodium sulfide nonahydrate under reflux conditions. The procedure is general, simple and convenient for the production of various poly(alkylene sulfide)s and the way reaction parameters influence the properties of the polymers formed has been examined.
