Figure presented 1,5-Selectively disubstituted 9,10-diphenyl-or alkylphenylphenanthrenes are obtained by reaction of ortho-substituted aryl iodides and diphenyl-or alkylphenylacetylenes in the presence of palladium and norbornene as catalysts. The reaction outcome is controlled by the steric effect exerted by the ortho substituent in the aryl iodide.
