Abstract Analysis of the 13 C NMR spectra of a series of 2,3‐dihydro‐1 H ‐pyrrolo[1,2‐c]imidazole derivatives has provided chemical shift data for (˜184 ppm), (˜173.5 ppm), (˜158 ppm) and (˜148 ppm) groups. A full analysis of the 13 C chemical shifts of the C atoms of the pyrrole ring and of an N ‐phenyl substituent is described.
