Abstract
Reaction of compound 1 with thiobenzarnide or substituted selenobenzamides
afforded substituted pyrrolobenzothiazole or selenazoles (2) respectively. Selenium
dioxide oxidation of the semicarbazone 4 with selenium dioxide gave 6-
benzenesulfonyl- 4,5-dihydro-pynolo [3,2-el benzoselenadiazole (5).
