Article abstract of DOI:10.1007/BF02251630

A mixture of phenyl substituted pyrazolo-4-azaphenanthrenes with different closure of the heterocyclic units was obtained by alkaline scission of 9-phenacylidene-4-azafluorene tosylhydrazone. Elimination of the nitro group occurs when 9-(α-nitrophenacylid
