Abstract
Abstract The formation of dibenzo[f, h]phenanthro[9,10-c]cinnoline from 10,10′-dinitro-9,9′-biphenanthryl and from phenanthrene-9,10-quinonemonoimine anhydride has been investigated. The structure previously assigned1 to the anhydride has been shown to be incorrect and structure VII is proposed mainly on the basis of physical evidence.
