This paper reports the synthesis and characterization of a series of new bis-benzo-1, 2, 3- triazin-3-yl) alkanes illustrated by structure 1 (ak). The prime method of synthesis is via diazotization of the bis-anthranilamide (2), which in turn is obtained by the reaction of isatoic anhydride (3) with the appropriate alkanediamine. Simple benzotriazinone derivatives of type 4 have been synthesized by several methods. A convenient one-pot method is to ...
