Significance
Reported is the copper bromide catalyzed synthesis of 2-aminobenzothiazoles from thiuram disulfides and ortho-halo aniline derivatives. As may be expected, a substoichiometric amount of disulfide is used (0.75 equivalents). The scope of the reaction was adequately tested in terms of aromatic electron-donating and -withdrawing substitution.
