    • note
    • 1H NMR spectrum of a saturated solution of 1b (ca. 50 mM) in DMSO at 20°C shows two but still overlapping signals for the guanidinium NHs (in contrast to more dilute solutions which only show one signal, see Figure 1). This might be a first hint to the formation of oligomers in such highly concentrated solutions.
