“…Diphenyl sulfide was converted into diphenyl sulfoxide in an excellent yield (Table 1, entry 4). In comparison, the formation of sulfoxides from diaryl sulfides has been reported in very long reaction times and relatively hard reaction conditions, and sulfone has been produced as a side product due to over-oxidation [35][36][37].…”

Bismuth(III) salophen as a new catalyst has been synthesized. Structural properties of this complex have been studied by Fourier transform infrared spectroscopy, X-ray diffraction, differential scanning calorimetry, and thermal gravimetric analyses. The average crystalline size of Bi-salophen particles was 86 nm. Thermal analyses show that the complex is stable over 300°C. Catalytic activity of this catalyst has been investigated in oxidation of sulfides. Different kinds of sulfides have been oxidized to the corresponding sulfoxides efficiently in the presence of sodium periodate as oxidant in glacial acetic acid as solvent at room temperature. These sulfides were selectively and completely converted into their corresponding sulfoxides in very short reaction times. Selectivity of this method was excellent, which is another advantage of this method.

“…[1][2][3] Therefore, the design of new catalysts for epoxidation of alkenes constitutes an important strategy for the synthesis of pharmaceuticals and fine chemicals. [4][5][6] In the field of homogeneous catalysis, salen and salophen ligands 4,[7][8][9][10][11] have been investigated for many years and are among the most widely developed ligands in the catalysis toolbox of modern chemistry for a range of organic transformations. Many synthetic approaches toward metallosalen complexes are known that start off with double Schiff base precursors.…”

Synthesis and application of new cationic Mn(III)-salphen complexes for catalytic epoxidation of olefins to epoxides in a homogeneous reaction media have been reported. The experimental data showed that the cationic salphen is more active than its neutral form. The acceleration of the reaction rate is attributed to the phase-transfer capability of the built-in phenazinium salt of the Mn(III)-salphen catalyst.Résumé : On a effectué la synthèse et examiné le domaine d'application d'un nouveau complexe cationique, le Mn(III)-salphène, pour la transformation catalytique d'oléfines en époxydes, dans un milieu réactionnel homogène. Les données expérimentales montent que le salphène cationique est plus actif que sa forme neutre. L'augmentation de la vitesse de réaction est attribuée à la capacité de transfert de charge du sel de phénazinium inclus dans le catalyseur Mn(III)-salphène.

“…Although the yields of these reactions were quite high, hexafluoro-2-propanol is poisonous, expensive and volatile, which severely restrict its practical use in organic synthesis. In continuation of our current studies on the selective oxidation of hydrocarbons [35][36][37][38][39][40] we wish to report herein a very efficient and simple method for the oxidation of sulfides to the corresponding sulfoxides using H 2 O 2 under mild conditions, as shown in Scheme 1.…”
