Rhodium-catalysed regioselective alkylation of the phenyl ring of 2-phenylpyridines with olefins

2-Phenylpyridines react with olefins react with olefins in the presence of rhodium(I) as a catalyst to give 2-(2-alkylphenyl)pyridines by a regioselective alkylation at the ortho position of the phenyl ring.
