Abstract

Abstract. Isothiazolium salts 2 and 3 are easily of 6ah4-thia-1, 6-diazapentalenes 5, a new typ of thiaavailable by reaction of (Z/E)-b-thiocyanatovinyl al- diazapentalenes anellated with a heterocyclic ring dehydes with primary aliphatic and aromatic amines system. The structure of 5 was evidenced by IR, UV, in acetic acid or with aromatic amine hydrochlorides,'H-, 13C-nmr spectral data and supported by elerespectively. Preparative ...
