The Suzuki-Miyaura reaction of N-methyl-2,3-dibromoindole with two equivalents of boronic acids gave symmetrical 2,3-diarylindoles. The reaction with one equivalent of arylboronic acid resulted in site-selective formation of 2-aryl-3-bromoindoles. The one-pot reaction of 2,3-dibromoindole with two different arylboronic acids afforded unsymmetrical 2,3-diarylindoles containing two different aryl groups.
