The first Suzuki-Miyaura reactions of pentachloropyridine are reported. The reaction with two equivalents of arylboronic acids gave 2,6-diaryl-3,4,5-trichloropyridines, while the reaction with one equivalent of arylboronic acid afforded 2-aryl-3,4,5,6-tetrachloropyridines. The one-pot reaction of pentachloropyridine with two different arylboronic acids resulted in the formation of 2,6-diaryl-3,4,5-trichloropyridines containing two different aryl groups. All reactions proceeded with very good site selectivity. [ABSTRACT FROM AUTHOR] |
