摘要

A direct and unambiguous synthesis of 9-isopropyl-10-methylphenanthrene (XI) has been accomplished. The instability of this hydrocarbon in the presence of boiling hydrobromic and acetic acids offers adequate explanation for the loss of isopropyl groups observed during the aromatic cyclodehydration of certain ketones and olefin oxides.
