SELENIUM HETEROCYCLE XL II [1]. SYNTHESES OF SUBSTITUTED THIAZOLO, SELENAZOLO AND 1,2,3-SELENADIAZOLOINDOLES
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).

متن کاملSyntheses of Copper(ii) Complexes of Acylhydrazones and Their Characterization
Copper (II) is a biologically active essential ion and it forms the active centers in several metalloenzymes and proteins. Its chelating ability and positive redox potential allow participation in biological transport reactions. The copper atom transforms between the Cu(I) and Cu(II) oxidation states in redox reactions involving copper containing enzymes. This is an essential factor for many of...
