Abstract

Abstract Substituted phenanthrenes and picenes were easily prepared by reaction of biphenylene or angular [3] phenylene with various alkynes in the presence of a catalytic amount of [IrCl (cod)] 2/dppe (cod= 1, 5-cyclooctadiene, dppe= 1, 2-bis (diphenylphosphino) ethane). The reaction is based on C [BOND] C bond activation of the cyclobutane ring. The reaction tolerates the presence of bulky groups on the alkyne, such as the ferrocene ...
