On treatment with SmI2 in THF and in the presence of methanol, 2,1,3-benzothiadiazoles underwent reductive N–S bond cleavage leading to 1,2-benzenediamines in high yields. Without methanol but in the presence of triphosgene, benzimidazolin-2-ones were obtained in moderate yields under mild conditions.
