Tetraaryl-substituted pyrroles are one important class of luminophores. In this work, an acid-promoted cross-dehydrative aromatization between benzoin and deoxybenzion was developed. This transformation provides an efficient and straightforward path for the synthesis of various aryl group substituted tetraarylpyrroles. Good to excellent yields were obtained through the easy operation with acetic acid and ammonium acetate.
