Henna-based compounds such as benzo[a]pyrano[2,3-c]phenazines, 2-amino-3-cyano-4-aryl- 5,10-dioxo-5,10-dihydro-4H-benzo[g]chromenes, hydroxyl naphthalene-1,4-diones, pyrazolyl naphthoquinones, benzo[b]xanthene-triones and their derivatives are of substantial interest as they possess a broad range of biological properties, such as anti-cancer, spasmolytic, diuretic, anti-coagulant and anti-anaphylactic activity [1]. In continuation of our efforts to synthesize of novel catalysts and MCRs, we wish to report the synthesis of novel nano molten salt tetra- 2,3-pyridiniumporphyrazinato cobalt tribromomethanide [Co(TPPABr)]CBr3 as an efficient catalyst for the synthesis of henna-based compounds under various conditions [2].
