title: The first solvent-free cyclotrimerization reaction of arylethynes catalyzed by rhodium porphyrins.
abstract: Different rhodium(III) porphyrin chlorides have been used as catalysts for the cyclotrimerization of several arylethynes, giving in many cases high yields in substituted benzenes and selectivities based on the steric hindrance of the macrocycles and on the substitution of the substrates.
