摘要
Electrochemical nickel-catalyzed syntheses of triphenylenes by a) reductive trimerization of ortho-dibromobenzenes or ortho-bromoarylsulfofluoridates, or b) reductive cross-coupling of ortho-dibromobenzenes to 2,2’-diiodobiphenyls, are described. The former provides a practical means for the construction of triphenylene derivatives in up to 87% isolated yield at room temperature. For 1,2-dihalo-3-methylbenzenes and related ortho-trisubstituted substrates, trimerizations proceed with high substrate-controlled regioselectivity for the non-C3h symmetric triphenylene isomer.
