Synthesis and proton magnetic resonance spectra of substituted biphenyls
Abstract
A series of new acylamino-, amino-, chloro-, and nitro-derivatives of 3,3′-dichlorobiphenyl have been prepared from 3,3′-dichlorobenzidine, and their structures have been confirmed by 1H n.m.r. spectroscopy. The electronic and steric effects of a nitro-group ortho to the internuclear linkage are discussed.
