| Abstrakt: |
Reaction of 9-diazo-4-azafluorene with phenylacetylene gives spiro[4-azafluorene-9,3'-pyrazolenines], isomeric according to the position of the substituent in the pyrazolenine ring. Their thermal rearrangement to pyrazolo-4-azaphenanthrenes that are isomeric according to ring linkage and position of the substituent in the pyrazole ring has been studied. |
