Substituted quinoxalinederivatives are traditionally synthesized by co‐condensation of various starting materials. Herein, we describe a novel environmentally benign in water synthetic route for the synthesis of structurally and electronically diverse ninety quinoxalines with readily available substituted o‐phenylenediamine and 1,2‐diketones using cheap and biodegradable itaconic acid as a mild acid

Covalent triazine frameworks (CTFs) based on polydentate ligands are highly promising supports to coordinate well-defined active metal complexes, hereby combining the well-known reactivity of homogeneous catalysts with the robustness and recyclability of heterogeneous catalysts. Herein, we describe the immobilization of a half-sandwich Rh(III) complex onto a bipyridine-based CTF and its application
