We studied how mixing ionic liquids affected the rate of the Diels Alder reaction between 9-\udanthracenemethanol and N-ethylmaleimide. The mixtures considered spanned the whole compositional\udrange and differed for the anion or the cation. These comprised mixtures of the ionic liquid 1-benzyl-3-\udbutyl-imidazolium bis-(trifluoromethanesulfonyl)imide ([Bzbim][NTf2]) with 1-(2,3,4,5,6-pentafluorophenyl)-\ud3-butyl-imidazolium bis-(trifluoromethanesulfonyl)imide ([Bz(F5)bim][NTf2]) or 1-benzyl-3-butyl-imidazolium\udtetrafluoroborate ([Bzbim][BF4]). Moreover we studied the reaction in a set of mixtures containing an\udaliphatic and an aromatic cation, namely [Bzbim+] and N-butyltriethylammonium ([bEt3N+]) sharing the\ud[NTf2\ud] anion. In this latter case we carried out RLS measurements, UV-Vis spectra of the solvatochromic\udprobe Nile Red and 1H NMR measurements to gain insights into how the structural organization of the\udmixtures changes as a function of composition. Altogether, these results show a concomitant effect of\udsolvent viscosity and structural organization on the rate of the process. Finally, no obvious correlation was\udfound between the kinetic trend and the polarity of the mixtures, as expressed by solvatochromic parameters
