Significance
An effective synthesis of various coronene derivatives is described. The pathway explored improves upon an older procedure, providing about a four-fold increase in yield by replacing the RuPPh3(cymene)Cl2 catalyst with TpRuPPh3(MeCN)2PF6. Functional groups tested include alkyl, alkenyl, alkoxyl, chloro, and phenyl groups. The generality of this method is also investigated on various related arenes with a high degree of success.
