Abstract
The X-ray analysis confirms the structure of the 12-methylene tautomer formed by the acid catalysis of 6-fluoro- ,2,3,4-tetrahydro-7,12-dime thylbenz-[a]anthracene. The central C ring is in a boat conformation, with the result that the molecule is bent about a line through atoms C (7) and C(12) with a dihedral angle of 32.5-degrees. The cyclohexene A ring is in a half-chair conformation.
