1. The mixture of acids obtained on the oxidation of
4:11 -dibromofluoranthene has been shown to consist
of 2:7- dibromofluorenone -l- carboxylic acid and
6- bromofluorenone -l- carboxylic acid. The structure
of the latter was proved by its decarboxylation to
3- bromofluorenone.

2. The action of diazomethane on fluorenone acids in
presence of methanol has been investigated.. The
ring enlargement to substituted 9- phenanthrols,
noted by previous workers, has been confirmed.

3. The reduction of 4:11 -dibromofluoranthene to 1:2:3:4 - tetrahydrofluoranthene has been accomplished.

dc.description.abstract
4. The synthesis of 4:11 -dicarboxyfluoranthene from
4:11 -dibromofluoranthene was successfully accomplished.
This di -acid was shown to be different from that
obtained during Friedel- Crafts reaction on
fluoranthene.

5. The tribromofluoranthene, obtained on the bromination
of 4:11 -dibromofluoranthene, has been shown, both by
degradation and by synthesis, to be 4:11:12-tribromofluoranthene.

6. 4:5- Dibromophthalic acid was prepared by the oxidation
of 4:5- dibromo -o- xylene and shown to be identical
with one of the oxidation products of 4:11:12-
tribromofluoranthene, thereby proving the structure
of the latter,

7. The nitration of 1:2:3:4 -tetrahydrofluoranthene gave
two products, which were shown to be 1- hydroxy -2-
nitro- 1:2:3:4 -tetrahydrofluoranthene and its
dehydration product, 2- nitro- 3:4- dihydrofluoranthene.

8. The dehydrogenation of 2- nitro -3:4- dihydrofluoranthene
to 2- nitrofluoranthene has made easily accessible
fluoranthene compounds substituted in the 2-
position. which are otherwise difficult to obtain.

9. The nitration of 5- bromo- 1:2:3:4- tetrahydrofluoranthene
also gave two products which are the bromo-analogue6
of those obtained in the nitration of 1:2:3:4 - tetrahydrofluoranthene.

10. The synthesis of 1:2- benzfluorene has been
accomplished, starting from ß - 1- fluorenonepropionío
acid.
