Room temperature diazotization and coupling reaction using a DES-ethanol system: A green approach towards the synthesis of monoazo pigments

An environmentally benign, one-pot diazotization and coupling reaction using ChCl:tartaric acid DES at room temperature is described. The bulky tartrate ion renders stability to the diazonium salt at room temperature, also evidenced by 1H NMR.
