Abstract

Hindered rotation about the C(sp2) − C(sp3) bond in 2-isopropylmesitylene (3), 1-isopropyl-2-methylnaphthalene (4), and 9-isopropylanthracene (5) is investigated by 13C NMR spectroscopy. At low temperatures, 4 exists as two rotamers 4a and 4b of different populations. Since their conformations are known from 1H NMR spectra, assignment of the 13C signals to 4a and 4b is possible. The knowledge ...
