Persulphateoxidation of a series of N- and ring-substituted biphenyl-2-carboxamides gave the corresponding phenanthridones in yields ranging from 2 to 97%. Usually the phenanthridone was accompanied by small quantities of the appropriate dibenzo[b,d]pyran-6-one, both products arising via the same amidyl radical, which can cyclise on nitrogen or on oxygen.
