Description
Amount of NH groups:In order to estimate the amount of NH groups in rGO-NH, a reaction with 4-bromobenzyl chloride was performed and the Br amount was quantified by X-ray fluorescence spectroscopy. The value obtained corresponds to 0.13 mmol/g.A heterogeneous bifunctional organocatalyst that is able to efficiently promote vintage organic transformations such as Knoevenagel, Michael and Aldol reactions.
