Abstract
Abstract 4-Aminophenanthrene, prepared by a new aromatization, has been converted to all four 4-halophenanthrenes: as halogen size increases, NMR spectra show increasing paramagnetic deshielding of the 5-hydrogens, while UV spectra indicate progressively greater molecular non-planarity. Oxidative cyclization of 4-iodophenanthrene gave salts containing the new cyclic 4,5-phenanthryleneiodonium ion.
