(9-anthryl)diphenylmethyl hexachloroantimonate (1) with nucleophiles gave mainly the quinoidal products by attack on the 10-position of the anthracene ring, suggesting the existence of a strong interaction of the two phenyl rings with the hydrogens at the 1- and 8-positions of the anthracene ring. Compound (1) is propellorshaped, and thus approach by the nucleophile to the benzylic site is difficult. For the reactions
