• contribution for the preparation of nitroalkanes, making alcohols a strategic source for their availability. Moreover, the mildness of our reaction conditions permits the survival of important functionalities. Furthermore, our protocol presents an interesting peculiarity from the sustainability point of view

• exposure time (12 h). The synthesis of [K+PEG]Br3− involves the reaction of [K+PEG]Br− with liquid bromine involving the indirect use of toxic bromine, which makes this reagent undesirable from the point of view of sustainability. However, the inexpensive nature, easy availability of PEGs, higher stability
