construction of polyfunctionalized quinoxalines has been developed. The key strategy includes the one‐pot domino N−H insertion, cyclization, and oxidation reactions. This protocol offers a safe and mild synthetic approach to access a variety of quinoxalinederivatives in high yields. This methodology also allows the formation of biologically interesting pyrazines and benzoquinoxalines.

Highly efficient vinylaromatics generation via iron-catalyzed sp3 C–H bond functionalization CDC reaction: a novel approach to preparing substituted benzo[α]phenazines
An iron-catalyzed benzylic vinylation was developed to transfer the carbon atom in the N,N-dimethyl moiety of N,N-dimethylacetamide (or N,N-dimethylformamide) to 2-methyl azaarenes to generate 2-vinyl azaarenes.
3-[(tert-Butoxy)carbonyl]diazenyl}but-2-enoates react in tetrahydrofuran at room temperature with aromatic 1,2-diamines to give 3-methylquinoxaline-2-carboxylates. These products were also obtained in solid-phase synthesis, by using polymer-bound 3-diazenylbut-2-enes.
