Visible-light-mediated facile synthesis of disulfides using reusable TiO2/MoS2nanocomposite photocatalyst

A nontoxic and inexpensive TiO2/MoS2nanocomposite was prepared and employed as an efficient photocatalyst for the synthesis of symmetrical disulfides under visible light irradiation at room temperature. Both aryl and alkyl thiols survived the reaction conditions, affording the corresponding disulfides in good to excellent yields. The photocatalyst could be easily recovered by simple centrifugation and filtration and reused several times without significant loss in its activity.

The reaction tolerates substitution in ortho-, meta- and para-substitution as well as electron-donating and electron-withdrawing groups. The S-cyclopropylation of a thiophenol was also accomplished using potassium cyclopropyl trifluoroborate.

Here, we report an iron-catalyzed cross-dehydrogenative coupling (CDC) reaction for the direct synthesis of C(sp3)?X (S/Se) bonds from oxindoles, phenylacetamides, pyrazolones, phenylacetonitriles and ethyl cyanoacetate with thiols and selenols. All the reactions were performed under simple and mild conditions, and air (molecular oxygen) was employed as an ideal green oxidant, thus promising broad application in chemical industry and modification of bioactive molecules.

PPS Preparation. A Kinetic Study and the Effect of Water on the Polymerization

A kinetic study on poly(p-phenylene sulfide) formation from p-dichlorobenzene (1) and sodium sulfide reveals that the initiation reaction is first order with respect to 1 and sodium sulfide, respectively.Reaction on the surface of solid sodium sulfide has proved to be neglible when the reaction is carried out in the presence of the solid.The time course of the concentration of 1 and its dimer can be explained with a simplified eight step kinetic model for the initial stage, in which each of the step is first order with respect of the reactant in concern.Kineticparameters for each of the steps were estimated.Increase in / ratio causes the increase both in polymer yield and in the degree of polymerization.Presence of a small amount of water enhances considerably the rate of polymerization and increases the polymer yield, but the highest degree of polymerization was observed in the presence of water approximately equimolar to 1.
