Benzo[c]cinnoline (114) (3%) was separated from a complex mixture of colored products obtained from the oxidation of 9 with active manganese dioxide formation of 114 suggests the stepwise loss of nitrogen, 10- 113-+ 1, and 1,4-dipolar cycloaddition of benzyne to 113.16 Oxidation of 9 with (diacetoxyiodo)benzene gave azobenzene (4%), 1-phenylbenzotriazole (112)... 

Ruthenium.— The oxidative addition of quinones to d and to metal centres is well documented. Now the oxidative addition of u-quinones to the d complex RuCl2(PPh3)3 has been reported. The reactions of ruthenium and iron cyclopentadienyl carbonyl dimers with azobenzene are described later (see manganese and rhenium).
