The reaction of Martin's sulfurane 1 with tert-butyl hydroperoxide, in the presence of 9,10-dibromoanthracene, emits light in two stages.The early stage, beginning on warming to about -40 deg C, coincides with the formation of olefin, and is intensified by degassing and quenched by oxygen or by organic sulfides.The later stage, seen on warming from -20 to -10 deg C, occurs during the formation of acetone from the hydroperoxide; this luminescence is eliminated by degassing and quenched by 2,6-di-tert-butyl-p-cresol and organic sulfides.Similar phenomena are observed with cumyl hydroperoxide.Relevant observations are reported on the NMR shifts produced in alcohol proton signals by diphenyl sulphoxide and dimethyl sulfoxide and on the CIDNP signals occurring during the reaction.Some conclusions are drawn concerning the mechanism of the luminescence.
Sulfoxide and Sulfone Synthesis via Electrochemical Oxidation of Sulfides

, p. 13790 - 13799 (2021/10/12)
The oxidation of diaryl sulfides and aryl alkyl sulfides to the corresponding sulfoxides and sulfones under electrochemical conditions is reported. Sulfoxides are selectively obtained in good yield under a constant current of 5 mA for 10 h in DMF, while sulfones are formed as the major product under a constant current of 10 or 20 mA for 10 h in MeOH. The oxygen of both the sulfoxide and sulfone function is derived from water.

A highly chemoselective, efficient and nano-Pd catalyzed protocol for the rapid construction of sulfoxides and sulfones via the oxidation of symmetrical and unsymmetrical sulfides using H2O2 as an oxidant has been developed, respectively. The ready availability of starting materials, easy recovery and reutilization of the catalyst, wide substrate scope, and high yields make this protocol an attractive alternative. The process also involves the metal-free and microwave-promoted synthesis of symmetrical diarylsulfides, and FeCl3-mediated preparation of symmetrical diaryldisulfides through the reaction of arenediazonium tetrafluoroborates with Na2S·9H2O as a sulfur source. In addition, unsymmetrical sulfides were generated via the K2CO3-mediated reaction of arenediazonium tetrafluoroborates with symmetrical disulfides.
