The advantages inherent to the solid phase procedure have since been applied to the synthesis of a wide variety of biologically important molecules. The unique aspects of polymeric supports have also been exploited to permit the conduct of a wide variety of synthetic reactions which take advantage of the resin support. Recently, these applications have led to the development of a variety of polymeric reagents where the reactive moiety is carried by the resin via a labile covalent linkage. [...] Part II: A number of syntheses of diaryl sulfides have appeared in the chemical literature of the last seventy years. Generally, these procedures have required harsh reaction conditions. The reaction of halonitro-, halodinitro-, and nitrodihalobenzenes to yield a variety of sulfides has been explored by a number of authors. The displacement of nitro groups from a variety of substrates has also been investigated. Specifically, several of these procedures have generated sulfides either as synthetic intermediates or as intended final products. The intermediate upon which this research was focused, 1,3-bis(thiophenyl)-4-nitrobenzene, was synthesized by means of a halo- displacement from halodinitrobenzene and a subsequent nitro- displacement to yield the desired bisulfide.
