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.
