A Novel bi-SO3H functional DABCO derived ionic liquid based on nitrate ion as a versatile reagent for rapid mono-nitration of phenols and naphthols


Department of Chemistry, Semnan University, Semnan, Iran


The mono nitration of phenols and naphthols has been reported in high yields and short reaction times using the task specific ionic liquid based on nitrate ion, 1,4-bis(4-sulfobuthyl)-1,4-diazabicyclo[2.2.2]octane di nitrate, as reagent without acid co-catalyst at mild condition. The reagent could be recovered and reused several times without significant lose of reactivity
