N.M.R. Spectra and Conformations of 9,10-Dihydroanthracenes

The preparation of a series of substituted 9,10-dihydroanthracenes is described and their proton n.m.r. spectra are dicussed.It is suggested that the trans-isomers of 9,10-dialkyl-9,10-dihydroanthracenes, substituted in the 9,10- or peri-positions adopt a polar ring conformation with the 9,10-dialkyl substituents placed over the ring.It is further suggested that the highfield signal of the β-protons of the 9,10-dialkyl substituents is due to partly to the magnetic anisotropy of the aromatic rings, and partly to the magnetic anisotropy of the carbon-carbon bonds from the alkyl groups to the 9- and 10-positions in the central ring.
