A highly efficient and chemoselective method for the synthesis of diaryl disulfides is developed via a visible light-promoted coupling of readily accessible arenediazonium tetrafluoroborates and CS2. This practical and convenient protocol provides a direct pathway for the assembly of a series of disulfides in an environmentally friendly manner with good to excellent yields.

O,O-Dialkyl-S-aryl-phosphorothioates are thermally unstable and decompose readily at a temperature of about 150° with formation of alkyl aryl sulfides and polymeric alkyl meta- or -polyphosphates. Differences in reactivity within a series of 33 phosphorothioates are rationalized on the basis of steric and electromeric effects. The mechanism of the thermal degradation is discussed, the influence of
