Abstract

Abstract The dimerization of arylethynes to give 1-aryl-substituted naphthalenes through catalysis by rhodium and ruthenium porphyrins has been investigated. When performed at temperatures above 130 C, this reaction affords a mixture of triarylbenzenes and 1-aryl- substituted naphthalenes. The yields of naphthalene derivatives range from low to high, depending on the temperature and the phenyl substituents. The concentrations of the ...
