32. The value of the number of electrons involved in each electron transfer in the different media used are calculated by comparison with the oxidation of redox probes, i.e. tris(4-bromophenyl)-amine, for more information see reference 27.
33. The presence of a reduction pre-peak between −0.5 and 0.0 V, depending on the RTILs, is related with reduction 4 in the presence of potassium. See reference 14.
34. The absence of the reduction wave associated with the 1,3,5-trinitrobenzene in the cyclic voltammogram indicates that there is no “free” nitroaromatic compound in solution.
35. H-complex yields the NASH products. It is also possible that some important part of the amine in excess could be protonated in RTILs and it would not contribute to shifting the equilibrium and increasing the reaction yield.
36. H-complex (NASH product-acetate) provokes the departure of the acetate.
37. The absence of the reduction wave associated to the 2,4,6-trinitroanisole after 1 h of preparation of the reaction mixture indicates that there is no “free” nitroaromatic compound in solution.
