Abstract

Unexpectedly, in the reaction of 2‐bromo‐2‐phenylacetonitrile derivatives with 2 mol‐equiv. of benzothioamide in DMSO, 3,5‐diaryl‐1,2,4‐thiadiazoles were obtained in excellent yields (83–90%) and in short reaction times (5–10 min). It is found that, in DMF, a quite different reaction takes place and 2,5‐diaryl‐1,3‐thiazol‐4‐amines are formed as the main products.

Reaction of pyran-2-thiones 4 with nitroso derivatives led surprisingly to type-8 (19) adducts which proved to be isomeric with the initially expected primary Diels-Alder cycloadducts 5. Methyl 2-thioxo-2H-pyran-5-carboxylate (40, when reacted with nitrosobenzene at -lo", led quantitatively to the t
