Abstract

Unlike open chain disulfides or even cyclic disulfides, which are readily oxidized by N2O4 and aqueous bromine to sulfinyl and/or sulfonyl derivatives, 1,2-dithiaacenaphthene is readily nitrated with N2O4 and brominated with aqueous bromine at the naphthalene ring. Other oxidants, such as Fenton system: H2O2-TiCl3, gave predominantly 1,2-dithiaacenaphthene 1-oxide as in the oxidation with H2O2.
