Electrophilic Sulfur Introducing Reagent

Bis(phenylsulfonyl) sulfide (1) enables the construction of thiophene rings or sulfide bonds in rigid units by the reacting with a variety of nucleophiles such as aryl lithium under mild conditions.¹⁾ It is therefore a useful reagent and a synthetic equivalent of sulfur dichloride (SCl₂), which is highly toxic and difficult to handle. In addition, benzenesulfinic acid, a by-product of the reaction, is soluble in water and can be easily removed by liquid separation. It has been reported that the thienoacenes synthesized by using 1 are used as OFET materials.²⁾
