Unexpected water addition to fluorinated 1,3λ4δ2,2,4-benzodithiadiazines with the formation of 2-amino-N-sulfinylbenzenesulfenamides

Fluoro-containing 1,3λ⁴δ²,2,4-benzodithiadiazines 2–4 unexpectedly add water to give previously unknown 2-amino-N-sulfinylbenzenesulfenamides 5–7 as the first derivatives of still undescribed 2-aminobenzenesulfenamide 10.
