Potassiumhydroxide is a competent and cheap catalyst for theintermolecular addition of arylamines to styrenes. The reactionsare performed in nontoxic dimethyl sulfoxide and can be used forthe large-scale synthesis of β-phenylethylamines.

availability of both phenols and amines, aniline synthesis through direct coupling between these starting materials would be extremely attractive. Herein, we describe a rhodium-catalyzed amination of phenols, which provides concise access to diverse anilines, with water as the sole byproduct. The arenophilic rhodium catalyst facilitates the inherently difficult keto–enol tautomerization of phenols by means of
