Abstract
This chapter will emphasize the recent advancements focusing on (i) transition-metal-based organic transformations of 1,2,3-benzotriazin-4(3 H)-ones, (ii) reactions of 1,2,3-benzotriazin-4(3 H)-ones under thermal and photolytic conditions, as well as (iii) acid mediated or metal-free reactions of 1,2,3-benzotriazin-4(3 H)-ones to fabricate highly functionalized five, six-membered N-heterocycles and ortho -functionalized benzamides. Further, this book chapter also discusses the denitrogenative reactions of 1,2,3,4-benzothiatriazine-1,1(2 H)-dioxides with suitable reaction mechanisms of the developed protocols.
