“…This is particularly true for the hydrazones. Hydrazine and phenylhydrazine reduce tetracyclone to dihydrotetracyclone under usual conditions (191,263). However, in dioxane-sulfuric acid the p-nitrophenyl-and 2,4-dinitrophenylhydrazones are formed readily (191,205,263).…”

“…Hydrazine and phenylhydrazine reduce tetracyclone to dihydrotetracyclone under usual conditions (191,263). However, in dioxane-sulfuric acid the p-nitrophenyl-and 2,4-dinitrophenylhydrazones are formed readily (191,205,263). The phenvlhydrazones of triphenyl-and tetraphenyIcyclopent adienone have been prepared through the cy clopent adienyldiazo compounds by adding phenyllithium and hydrolyzing (229).…”
