Abstract

We report a convenient single-flask methodology for the preparation of polyazatriaryl products with relevance to luminescence, catalysis, and pharmacology. The diborylation of 1, 3-dibromobenzenes and double Suzuki–Miyaura coupling produces 1, 3- diheteroarylbenzenes. Similarly, borylation of heteroaryl halides and double coupling to 2, 6- dichloropyridine produces 2, 6-diheteroarylpyridines. This methodology appears general ...
