Unexpected stable dimerisation of an anionic imidopyrrolecarboxylate in polar solution

Abstract

The imidopyrrolecarboxylate 3 unexpectedly forms stable dimers (Kass = 130 M−1 in CHCl3/DMSO, 1 : 1, v/v) despite the fact that two anions have to interact. The dimer is more stable than an analogous neutral amidopyrrolecarboxylic acid dimer (Kass < 10 M−1) underlining the importance of charged H-bonds compared to neutral ones.
