Abstract
Ring contraction followed by an elimination reaction on anti-9-methyl-18-trans-2-(10b, 10c- dimethyl-10b, 10c-dihydropyrenyl)-2, 11-dithia [3, 3] metacyclophane gave the desired compound 10b-methyl-10c-[2-(10b, 10c-dimethyl-10b, 10c-dihydropyrenyl)]-10b, 10c- dihydropyrene. 1H NMR spectroscopic analysis indicated a ring current effect over a considerable distance from the macro-molecular plane of each of the aromatic rings with ...
