In particular, the interest in pyrroloimidazole derivatives<br />(PID) arises from their highly efficient blue fluorescence emission [3], which makes them<br />attractive materials in optoelectronics for blue organic light-emitting diodes.<br />The strategies adopted for construction of fluorescent PID I, are depicted in Scheme 1. To<br />obtain ylides derived from benzo[d]imidazol 1, we used the Kröhnke [4] salt method. Thus,<br />benzo[d]imidazolium salts 3 were prepared by treating 3-(1H-benzo[d]imidazol-1-<br />yl)propanenitrile 1 with methylbromoacetate 2a or ethylbromoacetate 2b. Then, for the obtaining<br />of highly fluorescent pyrroloimidazole derivatives 5 and 6, it was used a (3+2) dipolar<br />cycloaddition of benzo[d]imidazolium ylides 4, generated in situ from the corresponding<br />cycloimmonium salts, to methyl propiolate or DMAD.</p><p>The structure of the new compounds was proven by elemental (C, H, N) and spectral<br />analysis (IR, 1H NMR, 13C NMR, 2D-COSY, HMQC, HMBC). All the elemental and spectral<br />data are in accordance with the proposed structure.<br />Acknowledgements: To CNCS - UEFISCDI, grant PN-II-TE/ 0010 -79/05.10.2011 (director<br />assisting profesor Costel Moldoveanu) for financial support.<br />References:<br />1.
