要旨:
An efficient two-step synthesis of 2,7-dibromocarbazole is reported. Nitration and Friedel-Crafts acylation of 2,7-dibromocarbazole proceed readily at the activated 3 and 6 positions to give new multifunctionalised carbazoles, which are of interest as monomers for new electrically active organic materials.
