The synthesis of benzo[c]phenanthre~~e and its derivatives has presented interesting problems, largely overcome by the use of partially hydrogenated intermediates (1, pp. 158-160; 2; 3). The successful ring expansion of benzo[c]fluorenone by the Schmidt reaction (4) and our earlier worl; with benzo[b]fluorene (5) prompted experi~nents with benzo[c]fluorene. 7-Acetylbenzo[c]fluorene (Ia) was prepared by the Claisen ...
