Abstract Mononitration of 9-substituted ethanoanthracenes, bearing Me, Bu t, F, Br, I, OMe, NO 2, CN, CHO or CO 2 Me substituents at the bridgehead carbon, was found to occur exclusively at the β-positions of the aromatic ring. The mononitro products were isolated, identified by 1 H nmr spectroscopy, and their relative proportions were estimated by quantitative glc. and/or by 1 H nmr spectroscopy. For all the above substrates the ...
