Abstract

Abstract: The Suzuki coupling of 2-and 4-chloropyridines with arylboronic acids is successfully performed under Pd (PPh3) 4 catalysis. Moderate to good yields are obtained with 4-chloropyridines while 2-chloropyridines give excellent yields. The corresponding pyridine N-oxides react in the same manner. An easy and cheap access to arylpyridines, a class of compound with medicinal interest, is thus achieved. Key words: chloropyridines, ...
