Abstract
Addition of [bis(saccharinyl)iodo]benzene to a methylene chloride solution of
Phen-Cu-Sac resulted in electrophilic aromatic substitution of saccharine onto toluene.
Similar reactions occurred with benzene and anisole. Umpolung reactivity allowed for
the formation of electrophilic saccharine cations. Sodium saccharine contaminated
[bis(saccharinyl)iodo]benzene afforded higher yields of the saccharinyl substituted
aromatic by allowing the saccharine cation to form from the copper (I) complex before
oxidizing to copper (II). A mechanism for the optimized reaction is presented.
