Syntheses and Spectral Properties of Several Unsymmetrical Sexiphenyls

Six sexiphenyls, including four new isomers, 2,3'-di(4-biphenylyl)biphenyl (2), 4-(2-biphenylyl)-o- (4), 4-(2-biphenylyl)-m-quaterphenyl (5), and 2-phenyl-p-quinquephenyl (6), were synthesized by the Ullmann cross-coupling of iodobiphenyl and diiodobiphenyl or of two kinds of iodoterphenyls.The characteristic bands of the infrared spectra (680-920 cm-1) and signals of the proton magnetic resonance spectra of the sexiphenyls were assigned tentatively and are discussed briefly.The remarkable high field shifts of the p-phenylene proton signals in 4 (1.23 and 0.89 ppm) as compared with that of p-terphenyl (δ 7.68) presumably reflect the ring current effects caused by the presence of adjacent o-phenylene rings.Ultraviolet spectral studies indicated that the absorption curves of the sexiphenyls were related closely to those of the polyphenyls corresponding to their partial structures.Keywords-Ullmann reaction; IR; UV; 1H-NMR; sexiphenyls; polyphenyls
