Abstract

The treatment of 9,10-diphenylanthracenes with DDQ in the presence of TfOH readily gave the corresponding rubicene derivatives in good yields. The effects of oxidant, acid, substituent, and other conditions are discussed. This protocol involving the Scholl reaction is convenient for the preparation of some rubicene derivatives from conventional starting materials.
