Samarium Diiodide Mediated Regeneration of 1,2-Benzenediamine and Preparaof Benzimidazolin-2-ones from 2,1,3-Benzothiadiazoles. — Efficient reduction
33- 043 tion
of 2,1,3-benzothiazoles (I) furnishing corresponding phenylenediamines (II) is
achieved with SmI2 in the presence of methanol. Direct trapping of these diamines by
triphosgene provides a facile access to benzimidazoles (IV). The methodology is compatible with reducible groups such as chloro, but nitro and cyano groups are reduced.
