Abstract
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-nitrophenacylidene)-4-azafluorene is condensed with tosylhydrazine.
