¹H-NMR study of some new acetyl dimethylbiphenyls: unambiguous signal assignment for the methyl groups

Abstract

The abundance ¹H-NMR spectra of some new mono- and diacetyl compounds derived from 2,2′-dimethyl-, 3,3′-dimethyl-, and 4,4′-dimethylbiphenyls were recorded. Unambiguous signal assignment of the methyl groups of the aromatic biphenyl rings were made for the structure elucidation.
