Abstract
The reaction of several substituted acrylonitriles 1 with arylthioamides 2 in acetic acid in the presence of perchloric acid yielding 2,4,5-trisubstituted 6-imino-6H-1,3-thiazine perchlorates 3a–3h is described. The structures of these compounds were established by spectral data, mass spectrometic fragmentation behaviour, X-ray structure analysis as well as by chemical transformation to the corresponding 3-benzoylaminothioacrylic acid amides 6 and 4-thioxopyrimidines 7.Keywords
