Abstract

Abstract We report the regiocontrolled syntheses of ethene-bridged para-phenylene oligomers in three distinct classes by using Pt II-and Ru II-catalyzed aromatization. This synthetic approach has been developed based on twofold aromatization of the 1-aryl-2- alkynylbenzene functionality, which proceeds by distinct regioselectivity for platinum and ruthenium catalysts. Variable-temperature NMR spectra provide evidence that large ...
