Abstract
The reaction of aromatic compounds and sulfur monochloride is investigated as a convenient route to prepare disulfides. Bis[4-[(4-bromophenyl)oxy]phenyl] disulfide (1), bis[4-[(4-bromophenyl)thio]-phenyl] disulfide (II), and bis-[[[(4-bromophenyl)sulfonyl]phenyl]oxy]phenyl] disulfide (III) were prepared through the electrophilic reaction of sulfur monochloride with aromatic compound catalyzed by SiO 2 . The thermal polymerization of the disulfide I results in the formation of high molecular weight poly(thio-1,4-phenyleneoxy-1,4-phenylene) (PPOS; M w =141 000) which is a high crystalline polymer with high stability after melting. The crystallographic data reveal that the resulting PPOS and poly(phenylene sulfide) both possess an orthorhombic unit cell
