A Blatter radical is oxidized to benzotriazin-7(H)-one which after amination and subsequent acyl- and aroylation gives N-(benzotriazin-6-yl) carboxamides that undergo ring closure with P 2S 5 to afford the corresponding thiazolo[5′,4′:4,5]benzo[1,2-e][1,2,4]triazin-4- yls. These highly delocalized radicals are air stable and show good reversible electrochemical behavior. © 2012 American Chemical Society
