Abstract
The purpose of this research was to investigate the stability and reactivity of 1-(pyrrolidin-1- yl) diazen-1-ium-1, 2-diolate (PYRRO/NO) in dimethylformamide (DMF, as the reference solvent) and compare them to those obtained using different ionic liquids. The results of our experiments showed that PYRRO/NO is more stable (based on reactivity) in ionic liquid [EMIM][Ms](with reaction yields up to 52%) than in DMF, that substitution products can be ...
