Route to Benzo- and Pyrido-Fused 1,2,4-Triazinyl Radicals .
As part of our ongoing studies on 1,2,4-benzotriazines, we required a reliable general route to benzotriazinyl radicals 1 that supported variation of the substituents at N-1 and C-3 and on the benzo-fused moiety. Herein we present a synthesis that avoids the formation of any unstable (highly reactive) intermediates such as the amidrazones 6 or the imidoyl/hydrazonyl chlorides 8 and 11.
