An efficient RhIII-catalyzed trans selective ortho-olefination of 2-aryloxypyridines has been developed. The catalytic system is very effective for olefination of differently substituted 2-aryloxypyridines with acrylates, acrylamide and styrenes and exhibits broad compatibility with assorted olefinic coupling partners. Although acrylates and acrylamide give rise to trans-olefinated products in MeOH
