Conclusions
-
1.
Reaction of 1-phenyl-2-benzoylacetylene and 1-phenyl-2-thenoylacetylene with, o-aminothiophenol in alcohol at 20°C in the presence of triethylamine in glacial acetic acid affords 2,4-diphenyl-6,7-benzo-1-thia-5-azacyclohepta-2,4,6-triene and 1-thenoyl-2-phenyl-2-(2′-aminophenylthio)ethylene respectively.
-
2.
The reaction of terminal α-acetylenic ketones with o-aminothiophenol results in the formation of 3-acylvinyl-2-acylmethylbenzothiazolines.
