of 3 and 4 show that fluorinated methylcholanthrenes containing fluorine in the angular benzene ring can be readily prepared. However, the failures to produce 11-fluoro-3- methylcholanthrene5 and 12-fluoro-3-methylcholanthrene (this paper) show that alternate synthetic schemes to the Elbs route must be developed. The failure to prepare the 10- methoxy compound parallels the failure to produce the 11-methoxy compound previously ...
